Sterling Silver and Black Zirconium Band.

The flat band is 8mm wide x 1.6mm, with the rope style Black Zirconium inlaid into the Sterling Silver.

ZiRO Black Zirconium rings are made in New Zealand from the mineral Zircon (ZrSiO4), which is found in S-Type giant stars and the sun.  When exposed to extreme heat, Zirconium forms a distinctive black coating which has a texture similar to ceramic.

Zirconium is harder than platinum. Black Zirconium rings are not plated or coated with any other substance. They are created through a heat-treating process that causes the ring’s entire surface to oxidise and, therefore, turn black. This allows us to create stunning two-tone designs by cutting into the metal to reveal the silver tone of the natural zirconium beneath the surface.
