The demand for Black Diamonds has seen a drastic jump over the last decade and is constantly accelerating. However, truly natural black colored diamonds are very-very rare as a result extremely expensive. Hence, to cater to the rising demand the not so perfectly black or grey or green real diamonds are treated to achieve a uniform black color. Almost 99% of the black diamonds used in jewelry or sold loose online or otherwise are treated black diamonds.
The black diamonds are typically heat treated which is also called HPHT (High Temperature High Pressure) or Irradiated.
Heat Treatment/HPHT- Heavily included real diamonds that are partially black, dull grey, brown, greenish or bluish in color are color enhanced to make them look black. The process involves placing the diamond in a High Pressure -High Temperature chamber with black carbon. After almost twenty-four hours the diamond is given an acid wash resulting in a uniformly colored jet black diamond. The treatment is permanent and is conducted on real diamonds.
