What Does Treated Black Diamonds Mean

An enhanced black diamond is a natural diamond that is treated with radiation to obtain a uniform black color.

What does treated black diamonds mean. Although made of carbon just like treated black diamonds natural black diamonds tend to have a more porous structure. Irradiation and heat treatment combined. 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.

Treated black coloured diamonds start as natural low clarity diamonds. 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. However the blue green color of this process is so dark that the diamond appears black.

Treated black diamonds on the other hand can look shinier depending on how dark their treatment has made them. To improve clarity or to alter color. As a diamond consumer you ve probably heard the term diamond treatment or treated diamond or perhaps enhanced diamond and wondered what that meant. Here diamonds of less good quality and purity are irradiated intensively usually with neutrons.

Because of this characteristic they also absorb light more fully and look completely dark and opaque. Black green and blue diamonds can be created by exposing the diamond to radiation. Likewise deep boiling does not fill in the cavity it simply removes the black compound that s filling it. However these treated black diamonds are just imitations of their natural counterparts.

Many treated black diamonds start as grey heavily included or fractured diamonds and undergo high temperature.
