What Does Treated Black Diamonds Mean

White diamonds of very low clarity go through a treatment process to change the stone colour.

What does treated black diamonds mean.

Irradiation and heat treatment combined. Here diamonds of less good quality and purity are irradiated intensively usually with neutrons. However the blue green color of this process is so dark that the diamond appears black. As a diamond consumer you ve probably heard the term diamond treatment or treated diamond or perhaps enhanced diamond and wondered what that meant.

If the inclusion cavity does not reach the outer surface of the finished cut diamond then the acid has no way of penetrating the inclusion. Diamonds which are purple pink blue yellow and brown can be created in this manner. This procedure only works on diamonds whose inclusions are black and reach the surface. Because of this characteristic they also absorb light more fully and look completely dark and opaque.

These stones are of a much better quality than a carbonado diamond because of the nature of their inclusions and the strength of these stones. First the diamond is treated through radiation and then it is exposed to high temperatures. A relatively small percentage of gem quality diamonds are treated and they are treated for two reasons. Although made of carbon just like treated black diamonds natural black diamonds tend to have a more porous structure.

To improve clarity or to alter color. An enhanced black diamond is a natural diamond that is treated with radiation to obtain a uniform black color. Black green and blue diamonds can be created by exposing the diamond to radiation. Many treated black diamonds start as grey heavily included or fractured diamonds and undergo high temperature.

Treated black coloured diamonds start as natural low clarity diamonds.
