With their vibrant colours and breathtaking beauty, fancy coloured diamonds have long been the centrepiece at auctions and museums. There is one category of gem however, that’s a touch less “prevalent”; pure black diamonds.

The history of black diamonds is rich, and a few popular black diamonds are shrouded in mystery. Black diamonds were first discovered in 1840 by the Brazilians. They were called carbonados. Black diamonds are found almost exclusively in Brazil and therefore the Central African Republic.

Black diamonds formed 2.6 to 3.8 billion years ago and are exceptionally rare. They are a natural polycrystalline diamond and there have been only about three metric tons mined, usually from the beds of streams. Larger black diamonds are literally made from many other smaller black crystals. Traditionally, diamonds are one, solid stone, but black diamonds are bound together by internal inclusions that hold many smaller pieces together.

This is why they are known as a polycrystalline structure and it is what gives them their colour and also the reason why spots can appear dark grey. Throughout most of the 19th and 20th centuries, jewellers regarded the black diamond as too difficult to cut and polish. It was deemed to be best suited for industrial use and was thought of as being mostly unsuitable for jewellery. You might also like the pale pink morganite engagement ring.

Is it an affordable choice?

Is it an affordable choice? Natural fancy black diamonds are relatively affordable, but obviously it depends on the dimensions wanted. Treated black diamonds, however, are significantly less expensive and the demand is quite low as most prefer the real thing.

How are Black diamonds graded?

The 4Cs of diamond grading still apply to black diamonds, but there are some differences. The grading are colour, clarity, cut, and carat weight. This is combined with the International Diamond Laboratory Grading System. These are the standards by which colourless to near-colourless (D-to-Z colour diamonds) are graded. Because black diamonds fall outside of this shade range, their colour is based on International Diamond Laboratory colour grading system for coloured diamonds.

The other aspect to consider is because black diamonds are opaque; they can’t be graded on the International Diamond Grading clarity scale. Also, there is variation in the tone and saturation of a black diamond. Therefore, they are only referred to as ‘fancy black’, which differs from other fancy coloured diamonds like pink, blue and yellow. A reputable jeweller such as Your Diamonds will be able to provide you with a Coloured Diamond Identification Report. The report will note if the colour is natural or treated.
