Black Zirconium is typically used in medical applications and nuclear reactors. It is perfect for jewelry because it creates a lustrous black layer when it is heat treated. This layer makes the ring very scratch resistant and allows us to create amazing two-toned styles. Black Zirconium offers the highest design versatility of any performance metal.
