What is Black Zirconium?

There are plenty of black rings on the market, but none of them stand the test of time like ours.

Machined from pure zirconium, a hypoallergenic metal similar to titanium but far more rare.

Black Zirconium Rings - How They're made

 

Machining

Starting with a solid bar of pure zirconium, we machine it down in a reductive process to create your ring.

Once the ring reaches its final dimensions and shape, it is hand finished for the desired appearance.

If your ring incorporates gold or platinum, these elements are added to the ring using a unique expansion process and seamlessly finished.

 

Oxidising

This is where the magic happens. Oxidation occurs when a metal reacts with oxygen in the atmosphere.

For example, steel left outside oxidises to produce iron oxide on the surface, a red coloured coating we call rust.

In the case of zirconium, the natural oxidation is invisible and actually protects the metal, making it extremely resistant to the elements.

When zirconium is heated in a furnace, this oxidation rate increases dramatically and the metal reacts to produce a much thicker oxide layer.

This oxide layer is called zirconium dioxide and is black in colour. Zirconium dioxide is also ceramic in nature, black zirconium rings don't feel like metal.

Furthermore, the oxide layer is extremely tough, it will not rub off with time and is extremely scratch resistant.

Why Monoblack

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".

Pricing

Our black zirconium rings are $375 entirely custom made. 


Monoblack has the hardness of sapphire with the internal strength of an aerospace metal.

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.
