  • ARE YOU GREEN WITH ENVY FOR GREEN DIAMONDS?

    Green diamonds traditionally symbolise peace, tranquillity, growth and fertility. They are amongst the rarest and the most highly-valued natural fancy coloured diamonds available ranking alongside blue, purple, pink, and violet diamonds in terms of rarity value. However, due to the popularity of blue and pink diamonds they have become somewhat obscured, although in actual fact they are rarer and this is largely due to the way in which green diamonds are formed.  Here we take a closer look at this most intriguing of the natural fancy coloured diamonds:

    How does a diamond get its green colour? 

    Diamonds are formed when organised carbon atoms are pressurised and bound together in the earth’s core. As we know colourless diamonds are chemically pure and structurally perfect.  Whilst in comparison natural coloured diamonds are formed when impurities occur in the chemical bonding, or defects in the crystalline structure. However, green diamonds are the exception. They acquire their unique colour from an extremely rare process of natural irradiation that occurs where carbon deposits in the earth contain highly radioactive material.

    A natural green diamond will be exposed to radiation over a period of thousands of years during its formation underground. The radiation, usually coming from uranium near the Earth’s surface, has the innate ability to displace carbon atoms in the diamond from their positions. This changes the stones ability to absorb and refract light which allows it to reflect the green colour on its surface. The longer the diamond is exposed to radiation, the more vivid the green colour becomes. The fact that these conditions have to be absolutely perfect for a green diamond to form is the reason that natural green diamonds are a genuinely rare occurrence and this is what makes this gemstone so intriguing.

    There is however no reason to be worried about the levels of radiation in green diamonds. Because this process takes place underground over thousands of years the actual diamond is rendered harmless. The green colour does not contain harmful chemicals and is merely the green light being reflected on the crystal, and the diamond retains only the radioactive stains NOT the properties of radioactivity.

    The majority of natural green diamonds are mined in Brazil, Venezuela and Zimbabwe

    How are green coloured diamonds graded?

    The Gemological Institute of America (GIA) has a special colour-grading system for fancy coloured diamonds including green diamonds. This takes into account the hue, tone and saturation of the rocks.  The term ‘hue’ refers to the primary colour of the diamond, the tint which appears on the surface i.e., blue, red, green, yellow. ‘Tone’ refers to how light or how dark the colour is, with the faintest grade nearing transparency while the darkest leans to black. ‘Saturation’ refers to how heavy the colour appears on the stone. The more vivid, deeper colours are graded higher on the chart.

    How is a green diamonds colour intensity measured for grading?

    The longer a green diamond is exposed to radiation then the deeper into the gem the colour will have penetrated and this will also determine the hue.  As green diamonds are less affected with impurities, it is often difficult to classify these diamonds according to colour and they can range from faint green to fancy deep green. Pure green diamonds are graded as follows: Faint Green, Very Light Green, Light Green, Fancy Light Green, Fancy Green, Fancy Intense, Fancy Vivid, and Fancy Deep.  Those classified Fancy Vivid Green are the rarest as they hardly ever occur so making them the highest priced.

    Very often green diamonds will also display two secondary colours these being blue and yellow.  You will therefore often see them colour graded as yellow, yellowish, blue, bluish, brown, brownish, gray, grayish, gray yellowish, and grayish yellowish.

    To establish the origin of colour green diamonds are always submitted to a gem laboratory. However even with today’s advanced technology it is not always possible for the lab to produce a satisfactory assessment.  Most of them are not green all the way through and many will show green radiation blotches or stains on the surface which get polished away during the cutting process, which lead to a loss of colour.  In these cases diamond cutters have to work their way around this in order to present the highest colour saturation in the best way.  It is highly unusual for a stone to be evenly coloured all the way through, but they do occur.

    What are Chameleon Diamonds? 

    To add to the intrigue, mystery and beauty of natural green diamonds some display another extremely rare phenomenon. This is their ability to change colour to suit their environment, hence the name given to this type of diamond - ‘Chameleon Diamonds’.

    Chameleon Diamonds are a variety of natural green diamonds that normally possess a green colour but can change from brown to yellow dependent upon their exposure to light and heat.  For example, when heated or kept in the dark, they can turn to bright yellow temporarily and as they cool down or are gradually exposed to light, they turn back to their original green hue. There is no exact explanation as to why this phenomenon happens and no other diamond possesses this ability which is the reason why Chameleon Diamonds are twice as rare and are highly sought-after by diamond enthusiasts.   A very famous Chameleon Diamond is The Chopard Chameleon which is a 31.31 carat oval shaped diamond.

    Famous natural green diamonds

    As green diamonds are so rare, only a handful of them are ever found.  Perhaps the most famous green diamond in the world is the ‘Dresden Green’. Believed to have been discovered in India in the 18th century this stunning green diamond weighs an amazing 41 carats.  It is the largest the known natural green diamond to have been discovered and has a clarity grade of VS-1, which was received by the GIA in 1988 as uniquely its colouration is uniformly distributed throughout.   It was acquired by Augustus, King of Poland and Elector of Saxony in 1742 and it remains on view in the Green Vaults in Dresden today.  It sets the benchmark for all stones of its kind because its colour is natural and homogenous all the way through.

    Also famous is the ‘The Ocean Dream’ whose name refers to its unique Fancy deep blue-green shade that resembles the crystalline image of a very, very deep ocean. It weighs 5.5 carats and was put on exhibition in the Smithsonian’s ‘Splendour of Gems’ exhibition.

    The ‘Aurora Green’ holds the title of the largest ever Fancy Vivid Green diamond weighing 5.03 carat. Its size is not the only remarkable property of this diamond is that it also has VS2 clarity and no fluorescence which is extremely rare for such a diamond.   It was auctioned by Christie’s Hong Kong on May 31st 2016 and sold for a very impressive $16.8 Million which makes the price per carat in excess of $3.3 million dollars!  This broke the record set at auction by ‘The Ocean Dream’ that sold in 2014 for $8.6 million, equivalent to $1.5 million per carat.

    As mentioned before another famous natural green diamond is ‘The Chopard Chameleon’ which was acquired in 2007 by Swiss jeweller Chopard. He revealed this stunning green diamond to the world in its delicate setting at Baselworld in 2008.  It is the centre piece of a ring surrounded by a delicate pavé setting of tiny fancy coloured diamonds and was designed by the renowned jeweller Caroline Gruosi-Scheufele. The Chopard Chameleon is the largest known chameleon diamond in the world, comfortably exceeding the previous record holder in size, a 22.28 carat chameleon heart shaped diamond.  It was estimated to be worth $10 Million in 2008.

    Famous celebrities who wear natural green diamonds 

    As green diamonds are so rare, they are not many who have been lucky enough to own/wear these amazing gemstones apart from royalty and the favoured few.

    The ‘Orlov Diamond’ is a bluish-green diamond which belonged to Catherine the Great of Russia and is set upon her Imperial Sceptre. There are a total of 180 facets on the diamond which features a rose-style cut and this diamond is said to have the proportions of half a chicken’s egg

    Queen Elizabeth is the lucky owner of a very rare chameleon diamond which was bought for Buckingham Palace anonymously. It is a very impressive 3 carat in weight and is heart shaped.

    In 2010 and in 2011, Gossip Girl’s Blake Lively was seen wearing a stunning green diamond ring which was designed by Lorraine Schwartz and consists of exquisite deep green coloured diamonds.

  • RED IS THE COLOUR OF LOVE AND ALSO OF THE RAREST DIAMONDS

    The colour red is generally associated with love, passion, and strength, therefore it is very fitting that the world’s rarest, most desirable and most valuable of the fancy natural coloured diamonds is the red diamond! Red diamonds are so rare that it is believed that thirty true ‘predominantly red’ diamonds are in existence, and most are smaller than half a carat - ‘predominantly red’ is the description given by the GIA that indicates that red is the primary colour in the diamond with no secondary hues such as purple.  

    Here we take a look at the phenomenon of the world rarest diamonds – the red diamond:  

    Why are red diamonds red?  

    In comparison to other natural fancy coloured diamonds there is very little gemological information about red diamonds largely due to their scarcity.  Colouring in diamonds is caused by various chemical impurities but as red diamonds are wholly comprised of pure carbon experts have long pondered how a gemstone with no such impurities attains such a striking and magnificent colour? 

    It is believed that the red colour is due to rare deformities in the gemstones anatomical structure which resulted from increased stress during the formation of the diamond. These lattice defects internally bend and refract the light that enters the diamond so giving it the red colouration.  Given different sources and amounts of light passing through, red diamonds appear to exhibit different colours and they shine more brightly under natural daylight, and under florescent light they appear much different and dull. 

    Often diamonds that may initially appear to be red to the naked eye are actually fancy deep or dark pinks. The difference between a fairly deep pink and a moderately dark red can be very subtle and almost undistinguishable to an untrained eye which is especially true under poor lighting conditions. 

    Red diamonds really are the exception to the rule  

    All natural fancy coloured diamonds have their colours prefixed by terms such as ‘intense’ or ‘vivid’ when compared in a colour grading scale.  Red diamonds however are the only exception to this rule and the reason behind this is that most gemological laboratories consider the red colour to be unique, as well as, “intense” or “vivid” itself.  However, there have been red diamonds found with slight differences in depth of colour with hues ranging from a lighter and sweeter tone to those with a much darker and deeper tint. 

    Where Are Red Diamonds Found? 

    The vast majority of red diamonds are found in the Argyle mines owned by the Rio Tinto company located in the East Kimberley region in the north of Western Australia and they are often featured in their famous annual Argyle tender. Red diamonds have also on rare occasion been found in the diamond mines of Brazil, Africa. Australia, Russia, and India 

    How much are red diamonds worth?  

    Out of all the natural fancy colour diamonds, red is the most rare, even surpassing pink diamonds. Red diamonds are one of the most expensive and rare diamonds in the world and they will always continue to break records although they rarely appear at auctions. In 1987 the 0.95-carat Hancock Red Diamond was sold for $880,000 in 1987 (you can only imagine what it must be worth now!).  The 5.11-carat Moussaieff Red Diamond was sold for $8 million dollars in 2001 and in 2013, a 1.92-carat Fancy Red rectangular-cut diamond, sold for CHF3.15 million at Christie's, while the auction house also sold a 2.09-carat heart-shaped Fancy Red diamond ring by Moussaieff for HKD39.32 million in 2014.  Since this time, only a limited number of red diamonds have been revealed, increasing their mystique. 

     

    What is the largest Red Diamond? 

    Red diamonds are so rare that there are only a handful of unmodified reds available on the market, with most of them weighing less than 1 carat in weight.   The world’s largest red diamond is the Moussaieff Red, which weighed in at 5.11 carats and sold for $8 million at auction in 2001 and is estimated to be worth over $20 million today!  It has a triangular brilliant cut sometimes referred to as a trillion or a trilliant cut and is rated in colour as a Fancy Red by the GIA.  Although this may seem relatively small when compared to other famous diamonds, in fact, the Moussaieff Red is the largest Fancy Red the GIA reports having valued.  

    Other famous red diamonds 

    Undoubtedly the most famous and largest red diamond is the ‘Moussaieff Red’ also referred to as the ‘Red Shield’) but other famous red diamonds include the Hancock Red Diamond, the Rob Red and the Supreme Purple Star 

    The Hancock Red Diamond is famous for its rare purplish red colour and weighs 0.95 carat. It is a round brilliant cut red diamond and was named after the famous collector, Warren Hancock who reportedly paid $13,500 for this diamond in 1956, which proved to be a great investment as he later sold it for $880,000 in 1987! 

    The Rob Red is a 0.59 carat fancy red diamond which is pear shaped and exhibits VS1 clarity. GIA colour grading experts described the Rob Red as ‘the most saturated and purest red diamond measured visually and instrumentally to date in the world’.   

    The Supreme Purple Star is a round brilliant cut deep purple diamond that weighs between 2 to 5 carats. The exact colour and clarity of this diamond has not been revealed but when viewing looking at the diamond from one angle, it appears to be of a deep purple colour, however when the diamond is rotated in the light, the colour changes to a very striking and lustrous deep to vivid purplish red colour. 

  • PRETTY IN PINK – THE BEAUTY OF PINK DIAMONDS

    Whilst red diamonds are acknowledged as ‘the’ rarest of all the natural fancy coloured diamonds, pink diamonds are considered by experts to also be one of the rarest natural diamonds on earth (along with purple, green, blue, violet and pure oranges). Due to this rarity it is estimated by experts that a pink diamond can cost at least 20 times the price of its colourless (white) equivalent and they are highly sought after by diamond collectors and connoisseurs worldwide for their personal collections and bespoke items of jewellery.  So what is it about pink diamonds that makes them so impressive? Let’s take a closer look:  

    Where in the world are pink diamonds found 

    Pink diamonds have been found in diamonds mines within Africa and India but the Argyle Diamond Mine owned by the Rio Tinto company and located in the East Kimberley region in the remote north of Western Australia, is the world’s only consistent source of pink diamonds. This mine accounts for more than 90-95% of the world’s supply of pink diamonds and also yields the highly rare red diamonds, blue, brown, cognac and champagne fancy coloured diamonds.  

    Despite only opening in 1985, due to the low yield of gem-quality stones, the Argyle Diamond Mine is expected to close by 2020 which further adds to the scarcity and rarity value of pink diamonds Argyle have estimated that “for every million carats of rough pink diamonds produced from the mine, only one polished carat is offered for sale by annual tender.” To put that in perspective, for every 200kg of rough pink diamond that is mined at Argyle, only 0.2g is offered for sale each year as part of the exclusive Argyle Pink Diamonds Tender. 

    How are pink diamonds formed?  

    Considering the rarity of pink diamonds geographically, the obvious question has to be whether the formation of pink diamonds has a direct relation to factors that are peculiar to the Kimberley region where the Argyle diamond mine is located?  

    Like white diamonds, pink diamonds are formed only of carbon within the kimberlite pipes of volcanoes. Pieces of carbon are transformed by extreme heat and pressure into the glass like diamond.   In contrast to other natural fancy coloured diamonds which obtain their colouring from traces of chemical impurities e.g.  a blue diamond from traces of boron in the soil being incorporated into the diamond as it forms, and yellow diamonds are formed due to trace levels of nitrogen,  experts have been unable to identify any chemical impurities in pink diamonds.  Many leading scientists believe that that the pink colour may be a result of historic seismic activity causing the defects which refract pink light. Given that the seismic activity varies wildly from area to area, this could explain why Kimberley and the Argyle mine is the world’s only significant source of these pink diamonds. 

    Famous Pink Diamonds 

    Perhaps the most well-known pink diamond is ‘The Pink Star’, formerly known as the Steinmetz pink diamond, which in April 2017 became the world's most expensive gemstone, selling at auction at Sotheby's in Hong Kong for $71.2 million (£57.3 million) including buyer's premium.  This magnificent gemstone is a huge 59.60 carat and is the largest Internally Flawless, Fancy Vivid pink diamond ever graded by the GIA.  It is rated as Internally Flawless as it has no internal inclusions, and is a Type IIa stone, the coveted classification given to less than two per cent of all gem-quality diamonds, which signifies chemical purity.  The Pink Star was cut from a 132.5-carat rough diamond mined by De Beers in Africa in 1999. It took two years of meticulous cutting and polishing to hone it into its current oval shape. 

    Before the Pink Star sold, the record price for a pink diamond at auction was $46.2 million, achieved by the 24.78-carat Graff Pink, which sold at Sotheby's Geneva in 2010. The Pink Star is more than twice as big as the Graff Pink, and its colour rating, Fancy Vivid, is the highest possible grade on the scale used to assess coloured diamonds, and therefore considered the most valuable. 

    The Graff Pink diamond falls in the top 1 to 2% of diamonds in terms of purity, according to the GIA. Its colour is exceptional and it features an emerald cut. This stone was previously owned by Harry Winston, a world renowned York jeweller who has possessed a number of famous diamonds. He kept it in his private collection for more than 60 years, when it was auctioned in 2010 in Geneva and purchased by Laurence Graff, a legendary diamond collector known as the “King of Bling.” He paid $46.2 million, which, at the time, was the most expensive diamond in the world. When Graff decided to buy this diamond he had planned to make it even more valuable than it was. Using cutting-edge technology, experts were able to eliminate potential defects considered as flaws, such as blemishes. Graff also planned to intensify the colour of the diamond, which can be achieved through cut. 

    Equally famous is the Darya-ye Noor, or “Sea of Light”, a 182 carat diamond which is pale pink in colour and weighs an impressive 186 carats. It is said to originate from the Golconda mines in India.  It was originally part of the crown jewels and was worn by many kings as part of their ceremonial dress until 1739 when the Persian army retrieved it and returned it back to Iran where research teams believe that the diamond was part of an even larger diamond that was divided into two pieces. Now featured as part of the Iranian Crown Jewels, the Darya-ye Noor is currently showcased at the Central Bank of Iran, in Tehran. 

    The Noor-ul-Ain pink diamond has also graced royal families. It is an absolutely stunning 60-carat oval brilliant-cut pink diamond which was given to Empress Farah Diba in the form of a tiara when she married Mohammad Reza Shah Pahlavi, the last shah of Iran. The centrepiece of the tiara is the famous pink diamond, surrounded by hundreds of coloured diamonds. 

    Other famous pink diamonds include The Martian Pink diamond which is a very rare 12.04 carat stone that was named in 1976 by US jeweller Harry Winston to commemorate the year that the Americans sent a satellite to Mars and was auctioned in Hong Kong for $17.4m (£11.1m).   The Rose of Dubai a pear-shaped Fancy Coloured Loose Pink Diamond weighing an impressive 25.02 carats, and the Princie Diamond which is a cushion cut fancy intense pink diamond boasting VS2 clarity which weighs 34.65 carat.  

    Are pink diamonds a good investment?  

    The answer to this question has to be a definitive yes.   Although pink diamonds are among the most valuable jewels today, 20 years ago they were little more than a geological curiosity. Sales have been driven by savvy marketing and a growing appreciation of their uniqueness. As the main source of pink diamonds the Argyle mine estimates that there are less than 500 tender quality diamonds yet to be unearthed in their mines, each day these extremely limited edition stones are becoming rarer still.  It is for this reason that those that weigh less than one carat can often command staggeringly high prices at auction reaching anywhere between $100,000 per carat to over $1,000,000 per carat, depending on the colour intensity, cut, clarity, and other given factors.

  • SHINE BRIGHTER THAN THE SUN WITH YELLOW DIAMONDS

    Are you the sort of person who likes to break the mould and turn heads wherever you go? Do you seek out the spotlight rather than shy away? Well if the answer to either these questions is yes then you may want to consider the choice of yellow diamonds for your engagement ring or other item of diamond jewellery.
    Natural fancy coloured diamonds are rare and yellow diamonds are amongst the rarest. They have become increasingly popular over the last decade with many A-listers choosing these stunning gemstones over the tradition of white diamonds. Jennifer Lopez is reported to love yellow diamonds and is often seen wearing a stunning 30 carat yellow diamond ring on the red carpet. Heidi Klum, Hillary Clinton, Kelly Clarkson, Cheryl Cole, even American R&B star Usher all enjoy the beauty of yellow diamonds. Of course, the most famous wearer of yellow diamonds must be Marilyn Monroe. She wore a fabulous 24-carat yellow diamond, famously known as the Moon of Baroda, to the Hollywood premier of Gentlemen Prefer Blondes. The diamond belonged to the royal dynasty Gaekwad Maharajas and Empress Maria Theresa of Austria. It was reportedly cursed, and was said to have been the source of Monroe’s misfortune and ultimately, her death.
    Nothing makes a statement quite like a yellow diamond and this is perhaps the reason that this is one of the most sought after of the natural fancy coloured diamonds. Natural Fancy yellow coloured diamonds come in various intensities: light Yellow, fancy light Yellow, fancy Yellow, fancy intense Yellow (also called Canary Yellow) and fancy vivid Yellow. In addition, yellow diamonds are often found with high clarity grading. Both facts have obvious impact on their pricing. With that in mind, the nice thing about natural Yellow Diamonds is that they are considered relatively affordable when examining the niche of natural coloured diamonds. However, prices do of course increase as the colours reach higher intensity colours. Some of the yellows with the higher intensity of colour (e.g. Fancy Vivid Yellows) are as rare as blue and pink diamonds and this will of course be reflected in the astronomical price that they can command!
    Although faint yellow in white diamonds is viewed as undesirable, fancy intense yellow is highly prized and sought after. South Africa today is currently one of the main producers of these natural coloured gems, India did yield some yellow diamonds in the 16th and 17th centuries, but this supply has been exhausted in recent times. The first authenticated yellow diamond was in fact found in South Africa and was the 10.73 yellow Eureka. By the early 20th century, South Africa had also produced the 128.51 Tiffany, the 130 carat Colenso, the 228.50 DeBeers, and the 205.07 Red Cross.

    Why are Diamonds Yellow?

    One of the main contributors towards the colouration of yellow diamonds is the presence of Nitrogen molecules occurring in higher concentrations than any other element during the diamonds formation. These molecules of nitrogen absorb blue light making the diamond appear yellow, yellow being the natural complement to the colour blue. The secondary colours for yellow diamonds include grey, green, orange, brown and even olive.

    Famous yellow diamonds

    Perhaps the most famous yellow diamonds was that discovered in South Africa in 1877 - the Tiffany Yellow diamond. This diamond was cut into a cushion style and weighs an amazing 128 carats. Set in what is known as the ‘Bird on a Rock’ setting, the diamond was made famous by the iconic movie ‘Breakfast at Tiffany’s’. Today, the piece, still in the ‘Bird’ setting, is on permanent display on the ground floor of Tiffany’s, New York.
    Other famous yellow diamonds include the Kimberley Octahedron which is believed to be the largest yellow diamond. This incredible gemstone weighs a phenomenal 616 carats. It is the 14th largest, gem quality, rough diamond in the world, and was discovered in 1972 in the Dutoitspan mine, South Africa.
    The Sancy diamond is another famous example of a stunning yellow diamonds and it has a rather romantic history. Weighing in at 55 carats, this yellow diamond fluoresces yellow and pink. The romantic part of the tale lies in the legend of its origins as it is thought to be an Indian diamond which Charles, Duke of Burgundy is said to have lost in on a battlefield in 1477. The name of the diamond comes from its first verified owner, Nicholas Harlai of Sancy who was a French ambassador. He purchased the diamond in Constantinople in the late 1500’s. It passed back and forth, being sold between France and England, ending up with the Astor family, who sold it, in 1978, back to France and it now resides in the Louvre.
    Due to their the growing popularity of yellow diamonds, more and more brides to be are changing their preference from the classic diamond engagement ring to yellow diamond engagement rings - adding a little touch of NOW to the classics.

  • ALL THAT YOU NEED TO KNOW ABOUT YELLOW GOLD

    In recent years yellow gold may have taken more of a back seat in popularity to other precious metals such as platinum. However, with the recent engagement of Prince Harry and Meghan Markle and their much talked about trilogy engagement ring set on a yellow gold band, this beautiful metal is set to make a resurgence in 2018. So, let’s take a look at yellow gold with our guide as to all that you need to know about yellow gold:

    What is Yellow Gold and how is it created?

    Yellow gold is gold in its purest form. The purest yellow gold being 24 karats at 99.9 percent, which is very soft and can be easily dented or scratched, therefore making it too soft to be used in jewellery making on its own. As gold is a highly malleable metal, it is easy to combine it with other metals to make it stronger and durable for the purposes of jewellery making. To make gold more durable it is infused with metals such as silver, copper and zinc in differing proportions to create an alloy which is harder than pure gold. The metals added to yellow gold make it more resistant to scratching and denting as well as adding to the overall appearance.
    Regardless of which metals are added to the gold alloy, its purity is measured in the same way as the percentage of pure gold to other metals determines the karat value of the gold. For example, nine karat yellow gold contains more silver, copper and zinc than 18 karat gold i.e. nine karat gold generally consists of 37.5% gold, 10.3% silver and 52.2% of other metals e.g. zinc and copper which give jewellery its characteristic yellowish tint. 14 karat yellow gold is generally 58.5% pure gold, 18 karat yellow gold jewellery is generally 75% pure gold and 24 karat gold is 100% pure gold.
    14 karat yellow gold jewellery is stronger and usually costs less than 18 karat yellow gold jewellery. However, 18 karat gold jewellery gives a more luxurious and heavier feel when worn and because you get more gold within an 18 karat gold item of jewellery, this makes it a better investment piece.
    Of course, the higher the karat value of the piece of jewellery (hence higher percentage of pure gold), the more care needs to be taken in looking after the item as yellow gold can be easily marked and dented. To keep the stunning shine and clarity of your piece of jewellery, yellow gold needs to be regularly shined and polished.
    The history of Yellow Gold

    Throughout history yellow gold has been treasured and admired by countless ancient civilizations across the globe, from the Greeks to the Mesopotamians, the Ancient Egyptians Pharaohs to Roman Emperors etc. Many cultures have imagined gold to represent the sun with its natural colouring and radiance and in fact the Incas referred to gold as the "tears of the Sun."
    Homer, in the "Iliad" and "Odyssey," makes mention of gold as the glory of the immortals and a sign of wealth among ordinary humans. In Genesis 2:10-12, we learn of the river Pison out of Eden, and "the land of Havilah, where there is gold: and the gold of that land is good?"

    Yellow gold is a timeless style that evokes opulence and wealth and across the centuries it has been worn in bracelets, rings, earrings, and necklaces, made into crowns, used in art, woven into thread and even inlaid in coffins and death masks.
    What are the key benefits of Yellow Gold?
    The key benefits of using yellow gold within piece of jewellery are as follows:
    The warm tone of yellow gold is classic and sumptuous and is very complimentary to warm skin tones
    Yellow gold looks great with white gold, silver, and platinum
    Yellow gold will always be popular and maintain value
    Yellow gold doesn't tarnish
    14 karat yellow gold is very popular, less expensive and has a warm look
    18 karat yellow gold is more popular globally and more valuable, it is purer and heavier and has rich, buttery tone.
    What is the difference between Yellow gold and White Gold?

    The key defence between yellow gold and white gold is that white gold is produced when yellow gold is infused with silver, nickel or palladium. The yellow gold used in jewellery is made in the same way, and the difference is only in the mixture of the additional metals used. For example, white gold has more zinc which makes the alloy look whiter than the typical yellow gold alloys which generally contain more nickel. However, even with zinc mixed in, white gold still has a yellowish tint. What makes white gold different is its plating, which is made of rhodium. This is a white metal that is used as a coating in jewellery and is actually the metal that gives white gold its colour. Rhodium also makes white gold more durable by covering the softer yellow gold alloy with an additional protective layer.

    Is Yellow Gold better than White Gold?

    As gold is a soft metal the higher the karat of the gold within your piece of jewellery, the more easily it will get scratched. Yellow gold can of course be polished, but this does remove a layer of the metal along with the scratches. In contrast, when white gold gets too many scratches, you can always polish them out and have the piece replated with rhodium, restoring the jewellery’s surface layer.
    Lower karat yellow gold is more durable, but if you are allergic to the nickel in gold alloys, a 10 karat or even a 14 karat piece may not work for you.
    Both yellow and white gold have their disadvantages, and while white gold fairs slightly better in terms of overall durability, neither is a perfect choice in this respect. This is the main reason as to why you should make your choice primarily based on colour. If you have a diamond of a lower colour grade (such as K or L), for example, have it set in yellow gold so that the diamond’s yellowish tint doesn’t stand out as it would in white. In contrast, if your diamond is graded Colourless (D-E-F grades) or Nearly Colourless (G-H-I-J grades), it would be a better idea to have it mounted in white gold, which will add to the stone’s white brilliance.
