Loose Treated Diamonds

Treated diamonds are real, natural diamonds whose color or clarity has been improved after mining. Color treatments include HPHT (high pressure, high temperature), irradiation and heating, which create vivid blue, black, pink, yellow and other fancy colors at a fraction of the price of natural fancy color diamonds. Clarity treatments include laser drilling and fracture filling.

Treated diamonds need a little care: tell your jeweler a stone is treated before any repair involving heat. Ask us about the treatment on any stone. Prefer untreated color? See natural black and natural brown diamonds.
