ZiRO - Black Zirconium & Black Diamond Signet Style Band
Black Zirconium and Black Diamond Signet Style Band.
Rectangular top signet with a 0.03 carat Black Diamond shot set in one corner, and engraved lines across the other.
Zieo 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.
The signet is 8.3mm wide at the top x 1.1mm thick.
