This ring is created from a pure metal called zirconium. Zirconium is a hypo-allergenic, bio-compatible, non-toxic element that is very rarely seen in consumer products. There is likely to be less zirconium in circulation than even platinum. It is very similar to titanium in behaviour.
The defining characteristic of zirconium, is that it turns black when heated. The metal reacts with oxygen once it reaches a high enough temperature, and this reaction forms zirconium dioxide on the surface of the ring. Zirconium dioxide is ceramic in nature, and as hard as sapphire.
For information on how black zirconium wears with time, refer to the durability and wear page.
A carefully controlled, crosshatch type brushed pattern is used to create a matte finish which is designed to scatter light in different directions, making the ring as non-reflective as possible.
It is available in matte, brushed and polished finishes.
