When purchasing a fancy-colored diamond, it is important to acquire an origin-of-color report from the GIA or one of the other qualified gemological laboratories. This report will indicate whether the diamond's color is natural or the result of human intervention. DoW ONLY carries diamonds with an Origin report of 'Natural', meaning that ALL of our fancy-colored diamonds are 100% natural and have NOT had any color enhancement treatments.
