Some people wonder whether there is such a thing as a black diamond, but it definitely exists. It can come from different sources; therefore, if you were looking to buy one, you would want to know the difference between a natural black diamond, a black diamond that has been treated, and a black diamond that is manmade. An article in the Guardian discusses the advances in the manmade diamond market.


When you ask what a black diamond is, a range of people may supply a range of answers. Generally, a natural black diamond is distinct from other coloured gems as it gets its colour from impurities, such as carbon and graphite, that are incorporated into the stone as it is formed.

A treated black diamond is usually an unexceptional white diamond that has been heated or irradiated to change its colour. A more accurate name for this might be a black coloured diamond or even a colourless diamond that has been treated. The manmade variety is essentially grown in a laboratory and some people may not consider this to be a real diamond. It can be coloured while it is being created.
