When couples come into Reve Diamonds to shop for an engagement ring we are often asked the question which is the more important factor to consider diamond clarity or diamond colour?   This question is often asked as the basis for a trade-off between these two factors when deciding upon a diamond. For example, should I choose between a diamond with SI1 clarity and G colour or and VS2 clarity and H colour?

    This is a hard question to give a straight answer to as there are circumstances when colour matters more than clarity and vice versa. However, what also must be borne in mind is that these are two unrelated attributes much as when going to buy a car for example the colour isn’t related to the fuel consumption, you need to consider both factors separately but meet both requirements to be happy with your purchase.   So in terms of diamonds a more educated approach would be to consider clarity and colour independently then decide what the minimum acceptable level is for each attribute. So to help you to do this let’s take a look at the facts:

    How is the clarity of a diamond determined?

    Firstly the diamond will be visually considered to see if it is ‘eye clean’. This means it will be examined with the naked eye from a distance of 9 – 12 inches without magnification to determine if any inclusions or flaws are present.  The diamond will then be more scientifically evaluated using a 10x magnification loupe to determine the extent of any inclusions, and also identify any additional flaws inclusions which may be present. The top clarity grade, FL (Flawless), is assigned to diamonds that have no visible inclusions when looked at with a 10x loupe. The lower a diamond’s clarity grade the more likely you are to see imperfections such as black spots or lines within the stone.

    How is colour graded in a diamond? 

    Diamonds are graded for an absence of colour, and then each colour grade represents a range of colour.  The scale begins with D-colourless which is considered to be the highest colour decreasing Z which is the lowest grade of colour and used to describe diamonds which are faint yellow. Diamonds are colour graded by placing them on a white tray upside down so that they are sitting on the table facet with the culet pointing up in the air.  This is under a diamond grading light which is controlled lighting that is colour corrected. They are observed from the side profile in a completely dark room, and then compared side-by-side with other diamonds known as a “master set” which have already been graded for colour.  The colour of a diamond is relatively easy to determine from a side profile under this type of controlled lighting environment but it is much more difficult to establish the true colour under normal lighting from the top-down.

    How to choose diamond colour and clarity

    Our first recommendation is that you ensure that the diamond is ‘eye clean’ so has no inclusions that are obvious enough to be visible to the naked eye. You do not necessarily need to go for the diamond with highest clarity as diamonds graded VS1-VS2 or SI1 can look just as clean as FL/IF-clarity stones if you choose a diamond that is pleasing to the eye.  If you are buying a round diamond for a yellow gold setting, you can safely pick a stone with a colour graded as low as J, K or L, possibly even an M and not worry about the visibility of any tints of yellow when the diamond is set into your engagement ring.  However, for other cuts of diamonds you may need to decide upon a higher colour grade such as I, J or K.  For a round diamond set in white gold or platinum or white gold then we recommend that you do not go any lower than the colour grades H, I or J. For other cuts G or H is a good choice, but don’t go lower than I colour.

    Should I focus more on clarity or colour when choosing the diamond for my engagement ring? 

    As we have previously said when shopping for a diamond engagement ring the focus upon clarity ‘v’ colour is very much down to your personal preference and quality of vision.

    If having an engagement ring with a white gold or platinum setting then selecting a high grade colour will be more important than having top clarity as it is very important for the diamond not to have visible tints.  If you set a diamond with slight yellowish tints in white gold or platinum, the yellow will stand out even more against the white backdrop, and the diamond will look darker than its setting. A small inclusion on the side of the diamond would spoil its appearance much less than the diamond’s low-grade colour in these circumstances.

    Clarity starts to matter a lot when it is too low. There is not much difference to the naked eye between a diamond graded IF or FL than one within the VS1-VS2 clarity range but diamonds with clarity graded below SI1/SI2 are very likely to have visible flaws.  Clarity is much more important when your engagement ring is to be yellow gold setting as this colour of metal can absorb the yellowish tints in a low-grade diamond making it look whiter in contrast to the gold. Therefor in this scenario you would be well advised to choose a diamond that looks clean to the naked eye rather than opting for a perfectly white colour.

    One selection factor that should be considered is the overall quality of the cut of the diamond. The reason for this is that the cut determines the amount of light that is refracted by the diamond which gives the diamond its sparkle and brightness.  So always choose a diamond that is cut to deliver the maximum volume of light return, brilliance and sparkle which will make it more difficult to locate inclusions. Plus well cut diamonds tend to look whiter than diamonds which are not so well cut.

    If you are still in doubt as to the importance of clarity and colour our highly experienced team here at Reve Diamonds are very happy to answer any questions and provide good advice on this, or any other diamond related matter.


    When the iconic actress Marilyn Monroe sang ‘Diamonds Are A Girl’s Best Friend’ in the movie ‘Gentleman Prefer Blondes’ she could not have been more true.  

    A truly beautiful diamond is breath-taking, and undoubtedly the fascination that women have had with diamonds for many centuries will never fade – unlike the love for some male suitors!  Who could fail but to yearn to possess one of the most stunning natural phenomenon? Irrespective of class every woman would love to have at least one diamond. Even non-westernised women, and those from cultures where wealth is not coveted, cannot fail to admire and be impressed by a piece of exquisite diamond jewellery.  Receiving the gift of a fabulous diamond engagement ring fills the daydreams of many young women, and even those who already a diamond engagement ring or other pieces of diamond jewellery, cannot fail but to be excited at the opportunity of adding to their collection.  So, what is it about diamonds that makes women love them so much – here are our thoughts: 

    Just what is it about diamonds!  

    The exact reason that women love diamonds is to be truthful unknown. It could be any one of many factors that create this affection and it is hard to pinpoint just one thing about diamonds that make them so irresistible. We think that at least one of the factors below helps to create this long-standing love affair:  

    Diamonds have always been surrounded by an air of mystique and wonder.   Possibly it is because of the formation process that diamonds go through that makes them one of the most desired commodities worldwide.  Whilst they are made of an ordinary everyday material – carbon, the process through which the carbon is transformed into a diamond and in some cases colours laid into the stone, is extra ordinary! 

    The formation of natural diamonds takes many thousands of years requiring extremely high pressure and temperatures.  Exactly the right environment is needed to create a diamond which is one of the hardest substances, and one of the most indestructible, on our planet.  So, maybe another reason that women love diamonds is that the time that is taken to form the perfect diamond, and the strength of this gemstone, can be seen to be akin to forming the perfect relationship between two human beings that will not break under pressure.  

    This symbolism of an indescribable connection between two people is part of the romantic message that diamonds express as the ultimate symbol of eternal love. For this reason, diamonds are the most popular choice of gemstone for engagement rings as nothing quite says, “I Love you, you are the one, please marry me!” than a diamond does.  Placing a diamond engagement ring on a woman’s finger tells her that you want to spend the rest of your life with her and symbolises to the world that she is loved and cherished as a diamond is the ultimate gift of love. Perhaps it is this symbolism and expression of deep love that we all crave that makes women love diamonds so much.  

    Does the expensive nature of diamonds have a part to play? 

    Whilst it may be seen as verging on crass to talk about diamonds in terms of the price that you will pay, perhaps ironically one of the reasons that they are so desired by so many women is that they are expensive. Of course, the expense of a diamond is related to its size, the brilliance of its colour, and the quality of its cut—the larger the diamond, the more brilliant the colour, the better the cut, then the more expensive the diamond. Correspondingly the more attractive and desired the diamond will be therefore price does play a part.   

    For some women the fact that their partner, fiancé or husband has spent a significant amount of money upon the gift of a piece of diamond jewellery signifies how great his love is. The gift makes a validation for the world to see of that woman’s worth in his eyes, so somehow cost can be compared to the value-added component in a love affair. 

    It is a well-known fact that women love to be admired by other women. Wearing a stunning diamond will certainly draw attention and satisfy that desire, and of course the more quality the diamond the more it will be a head turner. So, whilst it is impossible to say which of those attributes is the most important, the beauty of the diamond or its price tag, deep down we all know that cost does play a vital role (or a combination of both).  In today’s society there is still some degree of importance placed on material wealth, so no woman can truly be blamed for loving and coveting a diamond not only for its beauty but also for its value. 

    Does the answer lie somewhere between ancient history and eternal hope 

    Diamonds have played a significant part of ancient history right back to Egyptian times and maybe even earlier. When a woman wears a diamond engagement ring (or any other piece of diamond jewellery) she is making a connection with the past. Plus, she is forming a partnership with the miners, diamond cutters and jewellery retailers who have all had a part to play in that diamonds’ heritage. From raising the diamond from the earth, to cutting and fashioning it, to presenting that valuable piece of jewellery that it is today for purchase.  All these factors are interconnected with that diamond engagement ring.  Of course, there is also the element of eternal hope that the gift of a diamond engagement ring brings for a woman  - symbolising the beginning of a new life with her soulmate and hope for eternally happy times which long after she’s gone will still live on in that diamond ring, because as Shirley Bassey famously sang “Diamonds Are Forever”……. 


    Have you ever been in a jewellery store and heard the phrase “eye-clean diamond” and wondered what exactly it means and should you be investing in one? Here is a short guide to “eye clean diamonds” to help you better understand this terminology and its implications in your choice of diamond:

    What Is An Eye-Clean Diamond?

    “Eye-clean” is a term that is used in the jewellery trade associated with diamond grading.  It is used to describe the clarity of a diamond that is visibly clear to the naked eye when looked at from the top and without magnification i.e. a diamond that has no visible inclusions that can be seen unaided.  When looking for a good quality diamond this is an important consideration as some diamonds can disappoint with noticeable inclusions apparent when viewed with the naked eye.

    How Are Diamonds Graded For Clarity? 

    Diamonds are graded for clarity using a 10x magnification loupe which makes it easier to view naturally occurring clarity characteristics or inclusions.  The clarity of the diamond is evaluated on the specific internal inclusions and external blemishes which are then further assessed on their location, orientation and overall visibility.   The less inclusions/flaws that are found in a polished diamond the more rare the diamond becomes and in turn more expensive.

    Clarity should not be confused with brilliance and this is a common mistake.  Investing in a higher clarity diamond such as a VVS2, IF or VVS1 will not necessarily mean that you will have purchased a sparkling diamond.   It is the cut of a diamond that determines the amount of light that is reflected from the diamond so caused brilliance and only rarely does clarity affect transparency, so therefore diamond clarity should be solely viewed as a rarity characteristic.

    Is the term “Eye Clean” Subjective?

    Using the term “eye clean” to describe a diamond does bring with it an element of subjectivity relating to how precise and robust the definition of the term is.

    The reasons for this are that firstly visual perception and sharpness varies from person to person i.e. some people will be able to see tiny inclusions whilst others will require the assistance of glasses to enable them to detect flaws within a diamond.  Secondly, some inclusions can only be seen in certain levels of lighting which will also affect the brilliance of the stone - more brilliance means fewer visible inclusions, whereas less brilliance makes flaws more visible.  Therefore whether a diamond appears “eye clean” can vary dependent upon kind of lighting that the diamond is exposed to.  Thirdly,  the distance from which you view the diamond plays an important factor in that the closer you get to the diamond the more likely it is that you will see an inclusion.

    How Do I Establish If A Diamond Is Eye Clean”?

    Having said that the term “eye clean” carries a certain level of subjectivity, there is a method in which a diamond can be established as being within this category.   If you view the top of the diamond in broad daylight with a naked eye at a distance of approximately 20-25 centimetres if you cannot clearly see any inclusions or flaws such as clouds, lines or black dots  then that  diamond can be considered “eye clean”.

    What Clarity Grades On The G.I.A. Scale Are Considered” Eye-Clean?

    When matching the lower end of the “eye clean” clarity range to G.I.A. clarity grades the line is drawn at SI clarity, and more specifically SI2. Therefore any diamonds stones graded I1 and lower will not be considered “eye clean”.

    Diamonds with clarity grades of VS1 and above do not have visible inclusions and are always visually clean to the unaided eye.  Diamonds that are SI2 and higher will generally look relatively “eye clean” when viewed by the naked eye. It should be remembered that you may see some inclusions in SI2 diamonds when looking from the top depending upon the lighting. For the most part these inclusions will be quite hard to spot without using a 10x magnification loupe and therefore generally, SI2 diamonds will appear “eye clean”.  This is however considered a borderline grade and it separates the diamonds that are definitely eye clean (SI1 and above) from those that are definitely not (I1 and below).  However, please bear in mind that the term “eye clean” refers to viewing a diamond from the top only with the naked eye therefore in some cases a SI2-clarity diamond when viewed from the side may show some inclusions.

    It should be borne in mind that the clarity can vary dependent upon whether you choose a Step-Cut diamond (Emerald-cut, Asscher-cut, Baguette-cut etc.) in which it is easier to see inclusions, or a brilliant-cut diamond.  For step cut diamonds we recommend VS1 clarity to ensure the diamond is visibly clear to the naked eye and for brilliant-cut diamonds SI1 clarity. However each diamond is unique and must be evaluated individually.

    Does The Size Of The Diamond Have Any Influence On It Being “Eye Clean”? 

    The answer to this question is YES, the clarity of an “eye-clean” diamond does depend upon diamond size. For example at SI2 clarity or possible lower, a tiny 2mm diamond will appear “eye-clean” the reason for this is that the characteristics that define clarity are harder to detect within small diamonds.  In comparison when viewing a larger diamond e.g. of 3 or 4 carats that is graded SI1 flaws will be more easily noticeable due to the larger table size of the diamond and this is accentuated when there are small inclusions present directly below the table facet.

    Is Buying An “Eye Clean” Diamond A Good Investment

    As each diamond is as unique as the person purchasing it, there really are no hard and fast rules for buying a diamond, as they say ‘beauty is in the eye of the beholder’. However, as diamonds are mainly bought to be part of an engagement ring or other piece of jewellery, like many people you will most probably want to be sure that you get want best bang for your bucks!

    As the factors of carat weight and colour are more visually obvious to an onlooker, buying an “eye clean” diamond is an appropriate guideline as you will want to see a diamond that appears clean when viewed under normal conditions. Therefore perhaps place more importance upon the diamond you choose being “eye clean” rather than obsessing over its actual exact clarity grade.  To illustrate this it is easier to see the difference between a 1.00ct and a 2.00ct diamond just as it is to see the difference between a ‘J’ coloured and a ‘D’ coloured diamond with the naked eye.  However, if you compared a VS1 diamond with an IF diamond visually you would not be able to see the difference. This is what makes “eye clean” diamonds the most economical choice and the easiest compromise to make when choosing your diamond.

    It should always be remembered that “eye clean” is not an official grading category, and this is why you should decide whether a diamond is worth the price asked based on the clarity as graded and certified by an official body such as the G.I.A. .  We always recommend that you check the official grade of the diamond as to the untrained eye two different grades of diamond can look equally clean but in fact the higher graded diamond may be far more expensive. To avoid overpaying for additional clarity that cannot be seen to the naked eye, opt for the lowest grade diamond that is still “eye clean” in the range of SI1-SI2.

    Buying Tips For Eye-Clean Diamonds 

    1. The most prevalent inclusion in diamonds are crystals. We recommend that you choose a white/translucent or grey crystal over a dark/black crystal inclusion.
    2. It is generally preferable to select a diamond that does not have inclusions directly under the main table facet as this facet is the largest and easiest to see through.
    3. Choose a diamond which has small scattered inclusions rather than more concentrated inclusions.
    4. In S1 diamonds twinning wisps are quite common but they are almost always impossible to see without magnification so buying a diamond with these wisps is a great way to save money.
    5. Buying an eye-clean SI2 diamond stone doesn’t mean that its flaws won’t be seen from the side but if you wish to have this diamond set in a mounting that will hide its sides, then this would not be an issue. However, if the side view of the diamond is to be a feature of your chosen engagement ring or jewellery item, you would be well advised to opt for an SI1 diamond.
    6. I1 diamonds often have visible inclusions and are sometimes referred to as ‘prongable’ which means that an inclusion can be easily covered by a jewellery prong.  However, pay special attention to I1 or lower clarity grades as these can be more vulnerable to damage through wear and tear.
    7. “Eye clean” diamonds with lower clarity grades can offer tremendous value for money. Just remember, when it comes time to making your final decision on the purchase of a diamond, always consult with a diamond professional such as the expert team here at Reve Diamonds to ensure that your diamond is visibly clean and not vulnerable to breakage.

    As diamond experts one of the questions we get frequently asked is how to tell if a diamond is real or a fake! The bad news is that if you are not familiar with the structure and components of a diamond you may be led to think that a gemstone is a diamond when it is in fact an entirely different stone such as moissanite or cubic zirconia. In addition, it is almost impossible to spot a fake from areal diamond with the naked untrained eye as there is virtually nothing that you can feel or see to help you spot the difference. For this reason it is essential to know how to spot a fake diamond and the good news is that there are a number of simple tests that that you can carry out that can help you to spot a fake diamond. Of course no single at-home test should be regarded as conclusive proof either way, and we always recommend that you contact an expert such as the highly experienced team here at Reve Diamonds as we have professional experience and equipment to confirm if a diamond is real or fake.

    Here are some simple tests that you can carry out to help you spot a real from a fake diamond:

    Look at the diamond and setting through a loupe

    A loupe is a magnifying glass that you can buy at most jewellers and this piece of equipment will let you take a closer look at your prospective diamond and its setting. When looking at real diamond you will notice that due to the fact that diamonds are created by natural processes there will be some imperfections in the carbon. A fake diamond would not show such inclusions and would look to be perfect. It should be noted that laboratory grown diamonds will also appear to be perfect when viewed through the loupe, and therefore you need to exercise some degree of caution when discarding perfect gems as fakes so ensure that you bring the stone to an expert.

    Also observe closely the edges of the diamond as a real diamond will have sharp edges whilst a fake will show some rounded edges and fake diamond generally show abrasions or scratches.
    Lastly look at the settings and mounting of the stone in question. Take note of any marks that show what metal was used and if the metal is gold plated or silver there is a very high possibility that it is not a real diamond as no jeweller worth his/her salt would mount a true diamond in a cheap metal. The vast majority of diamonds are mounted in gold or platinum. Look inside the ring’s centre for markings e.g. the notes 10K, 14K, and 18K indicate the type of gold used and the markings PT and Plat refer to platinum. If you see a number such as 585, 770, 900, and 950, those markings also indicate platinum or gold as well. A ‘C.Z.’ stamp or engraving indicates that the gemstone is a cubic zirconia, and not a real diamond. In addition if the setting itself looks to be of poor quality, this probably indicates that it is not going to be a real diamond.

    The fog test

    For the fog test, hold the diamond or ring between two fingers and breathe on it with a puff of air the same way that you would if you were fogging up a bathroom mirror. A light fog will form on a fake diamond for a short time due to the moisture and heat in your breath, whereas a real diamond will not because it won’t retain the heat as real diamonds effectively conduct heat and therefore disperse heat quickly.

    The rainbow test - hold the gemstone in the light to see how it sparkles

    Diamonds reflect light in a very unique way. Inside the stone, the diamond will sparkle gray and white which is known as ‘brilliance’, while outside of the gem, it will reflect rainbow colours onto other surfaces and this effect is referred to as ‘fire’. A fake diamond will have rainbow colours that you can see inside the diamond and in fact moissanite and cubic zirconia, the two most common diamond simulants, actually throw more rainbows and more fiery stuff than a real diamond ever will as they are both slightly more refractive than real diamonds, hence that extra fire.

    The water test

    Find a normal sized drinking glass and fill it ¾ of the way with water. Carefully drop the loose stone into the glass. If the gemstone sinks then it is a real diamond but if it floats underneath or at the surface of the water, you have a fake diamond. A real diamond has high density, so the water test shows if your stone matches this level of density.

    Heat the stone and see if it shatters

    Diamonds are made of incredibly strong material and are unresponsive to high heat. To carry out this test use a glass full of cold water and use a set of plyers or heatproof gloves hold the stone. Heat the stone with a lighter for approximately 40 seconds, then it directly into the glass of cold water. If the stone shatters, it is made of weaker components and is not a real diamond. This is due to the quick expansion and contraction of heat, and weak materials like glass or cubic zirconium will crack and break. A true diamond will show no reaction as diamonds are one of the strongest materials on the planet so by their nature are resistant to such heat tests as they will disperse heat quickly and be unaffected by the change in temperature.

    Test the stone’s refractivity

    This test is most effective on loose diamonds. To test the diamond’s refractivity you can simply use the newspaper or ‘read-through’ effect. Place the stone flat side down onto the page of a newspaper with lots of text/lettering. Ensure the lighting is bright and that no objects or people are casting a shadow on the diamond. If you are re able to read the letters of the newspaper, even if it is a bit blurry, the diamond is a fake. If the diamond is real, its facets will refract the light in different directions, rather than in a straight line and due to this refraction of light, you will not be able to clearly see through the diamond to read the newspaper.

    Alternatively if you do not have newspaper to use, then the dot test is an excellent alternative. Place a white piece of paper on a flat surface and draw a small dot with a pen. Lay the stone onto the dot with the flat side down. Look down onto the paper through the pointed end of the diamond. If you can a circular reflection inside the gemstone, the stone is a fake. If you cannot see the dot or a reflection in the stone, then the diamond is real.

    While various tests can be used to tell if a diamond is real, we strongly advise that you use the services of a professional diamond expert assist you in determining if a diamond is genuine. Bringing your stone to a diamond professional will give you peace of mind, because several proven methods and tools are used to determine if a diamond is real such as using a thermal conductivity probe (aka “The Diamond Tester), testing with high profile weighing, using electrical conductivity, examination under a microscope or by x-ray. Of course the way to avoid buying a fake diamond is only to buy from a reputable source and to ensure that your diamond or item of diamond jewellery comes with a legitimate GIA or AGS certificate and to ensure the diamond matches the certificate.


    Even today the giving of a diamond engagement ring is seen as the ultimate expression of commitment, the symbol of how big your love is for your partner. With all the factors you must consider when buying a diamond, that nagging question still remains: Will the diamond I buy be big enough?  Does the size of the diamond really matter when buying an engagement ring?  

    Historically there is a common misconception in society that the bigger the stone, the bigger the love.   Maybe we should blame this on the very first person to give a diamond engagement ring, Archduke Maximilian when he proposed to Mary of Burgundy with a stunning diamond engagement ring in the shape of an “M”.  Since then, an engagement ring seems to be incomplete without a stunning and enormous, diamond sparkling out for it.  

    The common misconception of many people is to only judge a diamond by its carat weight as this is the easiest factor to spot, they equate carat weight with the “size” of a diamond.  When a sensational diamond engagement ring is seen on a woman’s hand, they immediately ask themselves ‘how many carats is that diamond?’  The truth is, you can achieve some of that same impact and dazzle by not only considering the carat weight but by focusing on other diamond factors that we call the ‘4cs of diamond grading’.   

    The ‘4cs of diamond grading’ will help any diamond amateur to judge if the stone is worth the investment. The basic 4 c's of diamond grading are colour, cut, clarity, and carat weight.  While the rest of the world think that carat weight alone should be the basis of defining the value of the proposal ring, this is not the case. There are other factors to consider before you choose your engagement ring – it is not all about the carat weight! 

    Diamond Colour 

    The "colour" part of the four C's of diamond grading, not surprisingly, refers to a diamond's colour. A diamond is priced also based on the "whiteness" of the stone. The top grade given to a diamond is the letter D, meaning the diamond is very white and conversely a Z-grade is given to diamonds with tints of yellow, grey or brown.  

    The vast majority of diamonds sold range between F and J. While a whiter diamond doesn’t necessarily compensate for size, it makes for a more beautiful and impressive diamond. However, differences between colour grades are very slight and hard to see with the naked eye, which means you can compromise a little on colour and still buy a beautiful diamond. 

    Diamond Clarity 

    In addition to its colour, a diamond is also graded based on its "flawlessness."  The grade "clarity" is given to determine the blemishes and internal inclusions that a diamond has.  The clearer the diamond, the more light has a chance of passing through it smoothly which is what causes the beautiful sparkle that many people desire.   However, if a diamond has a considerable number of flaws and inclusions, it could greatly influence its glimmer. Some people may have smaller diamond stones, but they can be very clear and very sparkly or another way to save money is to focus on well-cut diamonds of good colour that have a lower clarity grade. 

    Diamond Cut 

    For many women when it comes to diamond size and diamond sparkle, they will opt for the more brilliant stone.  A diamond engagement ring with a great cut can capture the attention of many admiring eyes even from a distance, as the way that a diamond is cut and proportioned directly affects how the light shines through it to cause the desired sparkle.   The more intricate the cut of the diamond ring, the more glimmer it will give out.  For example, in round diamonds, well-cut diamonds tend to be more expensive, but they also sparkle more, allowing you to compromise on carat weight and still get impact that will absolutely bring many "oohs" from admiring friends.  You  can make a big impression with your diamond engagement ring by choosing a well-cut centre stone flanked or surrounded by smaller and less expensive diamonds. 

    Other factors 

    Also consider the influence of shape of your diamond.  If you are going for the illusion of size, a fancy-shape diamond such as emerald, pear or marquise gives you a larger table size, or top surface area. This makes the diamond look larger, regardless of carat weight. Some settings, such as a halo, can also make diamonds appear larger. 

    So now that you have an overview of the 4 C’s it is your decision as to which factor holds most importance to you.   For example, if size is what really matters to you then you may give that the most priority and move down on the gradience with other C’s of course based on your budget. However do bear in mind that as we have pointed out diamond quality matters just as much, if not more, than size — in fact, the bigger the diamond, the more poor quality shows.  

    If your budget requires you to make trade-offs, always err on the side of quality to make a big impression with your diamond engagement ring.  For example, you might consider a high-quality (but smaller carat weight) centre diamond flanked or surrounded by smaller and less expensive diamonds. This can create the big wow factor you’re looking for, while still working within your budget. At the end of the day whatever your decision it is the thought and love that has gone into choosing your perfect diamond engagement ring that is much more important. 


    It is said that diamonds are a girl’s best friends and for many centuries, people all over the world have been enchanted by the mysterious allure of diamonds regarding them as one of the most glamorous, beautiful and breath-taking natural phenomenon.   Women the world over desire to wear diamonds and this gemstone is by far the first choice for engagement rings, is stunning in earrings or when worn as a pendant. However, there is also a lot of interesting facts about the origin of diamonds and their history that you probably do not know, so here are ten fascinating facts about diamonds

    1. The word diamond comes from the Greek word ‘adamas’ which means indestructible, unbreakable, or unconquerable. A very apt name for this precious stone, as diamonds are in fact hardest naturally occurring mineral on the planet. The only thing that can scratch a diamond is another diamond.
    2. The ancient Romans and Greeks believed that diamonds were tears cried by the gods or splinters from falling stars, and Romans believed that Cupid’s arrows were tipped with diamonds – possibly the earliest association between romance and diamonds.
    3. Diamonds were formed billions of years ago through a combination of tremendous pressure and temperatures of 1652–2372 degrees Fahrenheit at depths of between 90 and 120 miles beneath Earth’s surface. They are carried closer to the Earth’s surface through deep volcanic eruptions.
    4. Diamonds are made of a single element—they are nearly 100% carbon. Under the immense heat and pressure far below the earth’s surface, the carbon atoms bond in a unique way that results in diamonds’ beautiful and rare crystalline structure.
    5. Scientists have discovered a planet that they believe is composed mostly of carbon, and is one-third pure diamond!  Discovered in 2004, the planet orbits a nearby star in the Milky Way, and is named “55 Cancrie”. Perhaps even more amazing, is the fact that scientists have discovered a star that is essentially a diamond of ten billion trillion trillion carats.  They aptly named this star Lucy after the Beatles song “Lucy in the Sky with Diamonds.”
    6. Diamonds have been valued and coveted for thousands of years. In the first century AD, the Roman naturalist Pliny is quoted as having said, “Diamond is the most valuable, not only of precious stones, but of all things in this world.” Ancient Hindus used diamonds in the eyes of devotional statues, and believed that a diamond could protect its wearer from danger. Many ancient cultures believed that diamonds gave the wearer strength and courage during battle, and some kings wore diamonds on their armour as they rode into battle. During the Middle Ages diamonds were thought to have healing properties able to cure ailments ranging from fatigue to mental illness.
    7. The countries that are the main sources of diamonds have changed over time. Prior to the 18th century, most diamonds were found in India as this country was the world’s original source of diamonds, beginning in the 1400s when Indian diamonds began to be sold in Venice and other European trade centres. Then in the 1700s India’s diamond supplies declined and diamonds were discovered in Minas Gerais, Brazil which then became the world’s major source of diamonds, until the late 1800s when a huge diamond reserve was discovered in South Africa and the Great Diamond Rush ensued.  Today, diamonds are mined in many parts of the world.
    8. Only a fraction of all the diamonds mined worldwide are gem-quality. More than 80% of the diamonds extracted from the ground today are used for industrial purposes as they are not suitable for jewellery making.  They are used in industrial processes such as for drill bits and abrasives.
    9.  The largest diamond ever discovered weighed an amazing 1.33 pounds or 3,106 carats. It was called the Cullinan diamond, and was discovered in 1905 in South Africa. The mine’s owner and the South African leaders gave the diamond to King Edward of England. The Cullinan was eventually cut into nine large diamonds and 100 smaller ones, and the three largest of these are on display in the Tower of London as part of the crown jewels.
    10. The first known use of a diamond engagement ring took place in 1477, when Archduke Maxmillian of Austria gave Mary of Burgundy a gold ring featuring an M spelled out in diamonds.

    Each diamond is unique; it is a creation of time and place and therefore has specific qualities that establish its value. The Gemological Institute of America (GIA) created the first, and now globally accepted, standard for describing diamonds which is referred to as the ‘Four C’s of Diamonds’ – the measures of Colour, Clarity, Cut and Carat Weight.  This is the universally accepted method for assessing the quality of a diamond, so that jewellers can communicate to customers exactly what they are about to purchase.  All of these factors must be considered equally when comparing diamonds, but it is widely believed that more than any other factor; it is how the diamond is cut that will determine its defining characteristic.

    Colour :

    All diamonds are graded by their colour with the most valuable and rarest colour of diamond being white, that is to say, colourless which is of course the most popular colour of diamond used for engagement rings.  If you look very closely at a diamond you will find that not all white diamonds are created equally and grading allows the differentiation of whether a slight yellow hue can be detected.  Jewellers grade absolutely colourless diamonds with a "D". The scale then moves up to "Z" and, between these two extremes, diamonds will display subtle coloured tones. Diamonds with a very strong and distinct colour are extremely rare and are called fancies.

    Cut :

    The trademark glisten and sparkle of a diamond is not created by nature but by its ‘cut’ which influences its interaction with light and produces its characteristic brilliance.  It is easy to see why the quality of the cut of a diamond is so important as if a diamond is cut incorrectly, the defining sparkle will be compromised.  It is how the 57 or 58 facets which are the tiny planes cut on the diamond's surface are angled and sized that dictate how light reflects and exits the diamond, an effect known as its "fire".  If the cuts are made too deep or too shallow then it follows that the diamond will be less brilliant.

    The cut also determines the ‘shape’ of the diamond but cut and shape should never be confused, they are two different entities. The most common shape is the round cut, but others include the princess, the emerald, the pear, the marquise, the oval and the heart shape.


    This is the way in which the amount of imperfections, also referred to as ‘inclusions', in a diamond is measured. These imperfections are microscopic and therefore cannot be seen with the naked eye and are caused by foreign materials in the stone.  If you look into most diamonds with a jeweller's loupe which is a magnifying eyeglass, you will see small inclusions, they look like small clouds or feathers. Inclusions can affect the diamond's fire, but they also make each diamond unique and so should not be regarded as a fault.

    The higher the clarity grading, the rarer the diamond but providing that the diamond is graded SI1 (Slightly Included 1) or better (best and most expensive is IF, or Internally Flawless; worst is I3, or Imperfect 3), then the diamond is perfectly acceptable for use in a piece of jewellery.


    This is the measurement of weight, and thus the size, of a diamond. A carat is equal to 0.2gm or 200mgm and a carat is divided into 100 smaller units called points.  So for example, three-quarters of a carat is 75 points. The average size of most engagement ring diamonds is somewhere between one carat and half a carat.  It is important to remember that the size of a diamond may not necessarily correlate to its value as the cut grade of the diamond and its carat combine together to give it the brilliance and sparkle that we see in the finished product.

    When buying a diamond it is important that you request certification which proves that the diamond has been assessed, graded and coded with a laser by an independent gemmological laboratory such as the GIA HRD, IGL, EGL or AGS.  This will guard you against the purchase of a diamond that has been made with substitutes such as zircon, white sapphire, topaz or quartz which are natural minerals that can be nearly colourless and used as natural diamond substitutes. Synthetic substitutes include cubic zirconia and moissanite. All these are sold as legitimately cheap alternatives but be aware that they are sometimes, albeit rarely, passed off as real diamonds.

    Diamonds can also be artificially treated, most commonly by being fracture filled, irradiated or laser treated. All of this is legal, as long as it is disclosed to the buyer, but if you want a "real" and untreated diamond, guard yourself against terms such as "clarity enhanced".

    All diamonds sold by Reve Diamonds are fully certified.
