This is a black diamond 5.5mm rose cut round cabochon. Opaque and coloured diamonds have become very popular recently and it's easy to see why; the trademark flash of a diamond at a fraction of the price, and with an edgy, contemporary feel. Black diamond is very prone to nicks and chips and this stone does have some of those.
