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

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