We have tested and experimented with every realistic option for creating a black ring, ranging from ceramics to all sorts of coatings including diamond-like carbon. Black zirconium, or Monoblack as we call it, has proven to be the best by far. It is made entirely in-house so the lead time is as quick as possible, and we can combine it with precious metals.
Monoblack is made from a pure metal called zirconium. It is closely related to titanium and shares many similarities with one key difference. With specialised thermal processing, the surface of zirconium transforms into a ceramic which happens to be a beautiful black colour. The material is sometimes referred to as "black zirconium".
Our black zirconium rings are $375 entirely custom made.
How scratch resistant is it?
Black zirconium will withstand most daily wear and tear exceptionally well, but is expected to show degradation eventually. How long this takes varies depending on the individual wearing the ring and how carefully it is handled. Theoretically, only materials harder than sapphire can scratch through the ceramic layer, but constant abrasion and knocks against softer surfaces will eventually cause visible damage. If this is a concern, we recommend not getting a black ring.
