What Does Treated Black Diamonds Mean

To improve clarity or to alter color.

What does treated black diamonds mean.

Diamonds which are purple pink blue yellow and brown can be created in this manner. 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. Here diamonds of less good quality and purity are irradiated intensively usually with neutrons. As a diamond consumer you ve probably heard the term diamond treatment or treated diamond or perhaps enhanced diamond and wondered what that meant.

Treated black coloured diamonds start as natural low clarity diamonds. Because of this characteristic they also absorb light more fully and look completely dark and opaque. However the blue green color of this process is so dark that the diamond appears black. However these treated black diamonds are just imitations of their natural counterparts.

Treated black diamonds on the other hand can look shinier depending on how dark their treatment has made them. White diamonds of very low clarity go through a treatment process to change the stone colour. 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.

Likewise deep boiling does not fill in the cavity it simply removes the black compound that s filling it. A relatively small percentage of gem quality diamonds are treated and they are treated for two reasons. An enhanced black diamond is a natural diamond that is treated with radiation to obtain a uniform black color. This procedure only works on diamonds whose inclusions are black and reach the surface.

Irradiation and heat treatment combined.
