FANCY COLOURED BROWN DIAMONDS
In the past Fancy Coloured Loose Brown Diamonds have been very much over looked. This may be due to the fact that they are relatively common within the Natural Fancy Coloured Diamond family, which means that supply is less of a factor in determining price or desirability. In addition the colour brown may be not considered as glamorous and desirable as some of the other fancy colours. However, in recent times the popularity of Fancy Coloured Loose Brown Diamonds is very much on the up.
Where Are Fancy Coloured Loose Brown Diamonds Found?
Fancy Coloured Loose Brown Diamonds are found mainly in Australia in the Argyle diamond mine. They are also found in Angola, Borneo, Brazil and the Congo.
What Gives Fancy Coloured Loose Brown Diamonds Their Colour?
Fancy Coloured Loose Brown Diamonds are caused by ‘plastic deformation’ which is basically dislocation within the crystal structure of the diamond when it is forming underneath the Earth. This occurs when growing pressures within the earth create a movement within the crystal structure that change the diamonds molecular structure. This deforms the crystal structure from its regular pattern and introduces vibronic colour centres with unbonded electrons so creating the brown colouration. Fancy Coloured Loose Brown Diamonds can also be caused by nitrogen, hydrogen and nickel defects within the structure of the diamond.
Fancy Coloured Loose Brown Diamonds generally contain lower levels of nitrogen than other which causes the yellow colouring than other Natural Fancy Coloured Diamonds, making them more susceptible to deformation. Those which are light in colour are sometimes referred to as champagne diamonds, whereas browns that contain a significant amount of orange combined with a dark brown hue are called cognacs. It is relatively rare to find a Fancy Coloured Loose Brown Diamond that it is pure brown (a fancy brown without a secondary colour).
What Shades and Intensities Do Fancy Coloured Loose Brown Diamonds Come In?
Fancy Coloured Loose Brown Diamonds come in a vast array of shades and intensities and adopted different names that help describe their shades and tone. They can be found spanning the full spectrum of colour intensity on the GIA grading scale e.g. fancy light brown, fancy brown, fancy intense brown, and fancy deep brown (there are no fancy vivid browns)
Fancy Coloured Loose Brown Diamonds also come in many different varieties of colour combinations and overtones as Pink, Pinkish, Yellow, Yellowish, Purple, Purplish, Orange and Orangey.
What are Champagne and Cognac Diamonds?
Even though Fancy Coloured Loose Brown Diamonds were considered a natural beauty by some they were not widely accepted being predominantly used as industrial diamonds. In fact they were not even assessed on the GIA diamond colour scale.
However, the Australian Argyle mine where the majority of Fancy Coloured Loose Brown Diamonds are found changed the perception of Fancy Coloured Loose Brown Diamonds in the mid-1980s. They embarked upon a clever marketing campaign to change the consumer’s perception of Fancy Coloured Loose Brown Diamonds into an attractive and desirable item of jewellery by renaming these diamonds after aspirational luxury drinks that both men and women and can relate to.
The term ‘Champagne Diamonds’ was created to describe diamonds that are light brown, typically with a secondary tone of yellow, and ‘Cognac’ which are diamonds that are considered darker and deeper browns and often come with a touch of orange in them. An example of GIA colour descriptions that can be considered cognac diamonds: fancy orange brown, fancy deep orange brown, fancy dark orange brown, fancy dark brown.
Are Fancy Coloured Loose Brown Diamonds Rare and Expensive?
Generally speaking Fancy Coloured Loose Brown Diamonds are not considered to be a rare colour therefore according to market value demand; the prices of these diamonds are significantly lower than some of the more popular fancy colours making them a bargain for diamond collectors.
However, as with all Natural Fancy Coloured Diamonds there are some shades within the brown family which are considered rarer than others and large brown diamonds that receive a high clarity grade will always attract a higher price. It also goes without saying that the stronger the colour, the more expensive the diamond e.g. a dark or deep brown diamond will be more expensive than fancy brown that is more expensive than fancy light brown.
In addition the rarer the secondary colour is, the more expensive the diamond. Yellow is much more common than pink and therefore a yellow brown diamond aka a ‘Champagne Diamond‘ will be of a lower value than a diamond with similar attributes that is graded as pink brown. The same applies with yellow brown compared to orange brown as seen in a ‘Cognac Diamond’ as orange is rarer than yellow so a yellow brown diamond is of less value than an orange brown diamond.
