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.
What does treated black diamonds mean.
Black green and blue diamonds can be created by exposing the diamond to radiation.
This procedure only works on diamonds whose inclusions are black and reach the surface.
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.
First the diamond is treated through radiation and then it is exposed to high temperatures.
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.
Here diamonds of less good quality and purity are irradiated intensively usually with neutrons.
However these treated black diamonds are just imitations of their natural counterparts.
To improve clarity or to alter color.
Treated black diamonds on the other hand can look shinier depending on how dark their treatment has made them.
Irradiation and heat treatment combined.
Because of this characteristic they also absorb light more fully and look completely dark and opaque.
Many treated black diamonds start as grey heavily included or fractured diamonds and undergo high temperature.
However the blue green color of this process is so dark that the diamond appears black.
Diamonds which are purple pink blue yellow and brown can be created in this manner.
White diamonds of very low clarity go through a treatment process to change the stone colour.
