Glittering Black Beauty

It’s only relatively recently that black diamonds have become prized as gemstones in their own right. Traditionally either thrown away or used solely for industrial purposes, it’s really only in the past thirty or so years that they have come into their own. Now called ‘fancy blacks’, they began their popularity streak when designers started using them to contrast with colourless stones in pave settings and have got bigger and better ever since, in fact you might say they finally ‘arrived’ when Mr Big gave Carrie a 5 carat black diamond ring at the end of Sex and the City 2! Since then, there have been more high-profile black diamond engagement rings and of course, prices have risen in line with their popularity. They are unique stones, having the adamantine brilliance you’d expect from a diamond, despite the fact that they are black and opaque. They glitter, like mirrors, with a silvery lustre. Still, there are relatively few famous black diamonds, one of which is the Black Orlov which comes laden with the usual kind of myths and legends of curse and disaster.

But what is a black diamond? Conversations with customers over the years have told me that this gemstone is not well-understood. Natural black diamond is, in fact, simply diamond that is so included with mineral inclusions, such as haematite, pyrite and graphite that it appears black. It is also often criss-crossed with minute cleavages and fractures that are either stained black or have become black due to graphitisation (the formation of graphite due to a process too arcane for me to wrap my feeble head around). And in fact, a great deal of black diamond on the market is irradiated, so that the inclusions turn black. I always state the black diamond I sell as irradiated, as I am generally not sure and better to be safe than sorry…

The upshot of this is that black diamond is rather brittle, and it is this that causes confusion. Yes, diamond is hard; very hard. But hardness is not the same as toughness. Glass is hard but will shatter if you drop it; putty is soft but you can drop it and it will remain in one piece. Black diamond, filled with inclusions and riven with tiny fractures is pretty brittle. Don’t drop it, don’t – as a friend of mine did – slam it in a car door and do set it with care. You can also expect it to be rather prone to pitting, certainly on the base and around the girdle and often on the facets edges and corners. But if you can live with all that, you’ve got a gemstone like none other. Below, I love the contrast of the black and white diamonds, accentuated by the use of silver and oxidised metals in this Coco & Chia stacking ring set.

You can clearly see, top, the included nature of black diamonds in this beautiful rose cut black diamond ring from Lex Luxe – you can actually identify the blackened, frondlike clouds of inclusions. Another option from this jeweller is this black and white diamond cuff bracelet, with the contrasting colours offset by oxidised metal. And, right, just because it’s black, doesn’t have to go in white metal; this black diamond cluster ring (bottom) by Ferkos Fine Jewelry is set in 14k gold.

At Joopy Gems we carry rose cut black diamonds in a range from 3mm-5mm. These are sized pretty precisely as small differences make a disproportionate difference in terms of price when the carat price is high. The 3mm and 4mm stones are of slightly higher quality than the other sizes but you can expect the odd pit and fracture as is normal with this stone. To browse the entire range, click here.
