Black Zirconium great choice of  metal that men are increasingly choosing as their ring of choice. Black Zirconium durable, a good level of scratch resistance and looks great. Similar in weight to titanium, all our Black Zirconium rings are hypoallergenic. Black zirconium turns to a permanent black through the heating process that causes the rings entire surface to oxidise and turn black. This allows for amazing two-tone designs to be created.
