There are plenty of different
Here’s what you need to know about black wholesale diamonds found at Diamond Brokers Queensland.
ARE BLACK DIAMONDS THE REAL DEAL?
While they may not be too common just yet, black diamonds are certainly real. You get genuine black diamonds found naturally in white diamonds and white diamonds that are artificially changed to look black. Both are the real deal. But there are a few differences you should know about.
WHAT YOU NEED TO KNOW ABOUT NATURAL BLACK DIAMONDS
Also called fancy black diamonds, you will only find natural black diamonds in Africa or Brazil. While vastly different in colour, these diamonds have the same chemical composition as their white counterparts. However, they have a different polycrystalline structure which means they do not reflect light. They also have a great deal of inclusions, like amorphous carbon and clusters of graphite.
WHAT YOU NEED TO KNOW ABOUT TREATED BLACK DIAMONDS
White diamonds that are changed to black are known as colourless treated black diamonds. White diamonds also have a high amount of inclusions and are therefore used to create black diamonds, but these tend to be of a much lower value than natural black diamonds.
White diamonds can be turned into black diamonds with treatments such as irradiation or heat. Treated black diamonds can be found in jewellery, but mostly they are used as industrial grade diamonds in grinding and cutting tools.
BLACK DIAMONDS AND THEIR QUALITY AND PRICING
Black diamonds tend to be more affordable than white diamonds due to their structure and colour, especially treated black diamonds. But they are by no means low-quality stones since even the treatment process does not affect their durability.
However, since black diamonds contain main inclusions and tend to be porous, cutting and polishing the stones is a lot harder, and that can lead to surface nicks and blemishes. On the bright side, professional cutters are able to craft black diamonds with a polished, smooth surface.
As for pricing, you can pay anywhere from $300 up to $500 per carat for a small black diamond under half a carat. For 5 – 6 carate black diamonds, you could pay in the region of $700 to $800 per carat and upwards of $30,000 per carat for a white diamond of a similar size. Sometimes, a one-carat black round diamond with a good finish can cost close to $2,000.
