Diamonds are usually treated to make them more attractive to the eye or remove small fractures or minor imperfections like foreign material.
What does color treated diamonds mean.
Treatments can enhance color clarity or both.
Irradiation or exposing the diamond to radiation followed by high pressure high temperature treatment can turn brown and yellow diamonds into fancy colored diamonds.
This procedure is what is done to diamonds whose black inclusions do not reach the surface of the diamond.
With advances in technology there are various types of treatments and enhancements that can be used to alter a diamond s color completely.
Clarity is enhanced by filling techniques fracture or laser while color is affected by treatments like coating irradiating or high pressure high temperature hpht treatments.
Outside of a well equipped grading laboratory this form of diamond treatment is virtually undetectable.
Only a small number of diamonds will yield the very popular purple pink color when they re treated so this color of diamonds is more expensive compared to some of the other colors.
Hpht stands for a high pressure high temperature.
Well these diamonds are expensive and very rare.

Clarity enhanced diamonds are stones that have been treated with heat or certain substances to make these diamonds look clearer than they naturally are.
This treatment is an effective tool for changing the color of certain diamonds making them colorless pink blue green yellowish green or yellow.
