IGI Education - Are Lab Grown Diamond Color Treatments Permanent?
As lab grown diamonds continue to gain popularity, jewelers want to know if modern processes that alter the diamond’s color are permanent.

Brought To You By IGI
Efforts to improve color in natural diamonds began centuries ago with oils, dyes and bright foils applied to the pavilions of diamonds in closed-back mountings. In modern times more sophisticated chemical coatings may be used to lighten the apparent color of diamonds in the D-Z range. These treatments can be scratched, worn off or changed with heat or chemical exposure, so they are not considered permanent. As such, IGI will not issue a grading report for such diamonds.
