For exceptional quality, the diamonds set in our jewelry meet strict minimum quality standards. Each diamond is colorless to near-colorless (D–I grade color) with exceptional clarity (FL–I1 grade clarity). This standard of quality applies to all our diamond jewelry — even pieces with the smallest diamonds.

Black diamond fashion jewelry is crafted using natural diamonds that have been treated to create the unique black color with a high luster. It is common for black diamonds to reveal minor surface imperfections without magnification.
