Spectrum - 7mm Bevelled Black Zirconium

Spectrum - 7mm Bevelled Black Zirconium


Spectrum is made from our "Monoblack" Black Zirconium, a metal-ceramic hybrid. It has a flat profile with chamfered edges, the edges are polished in contrast with the brushed finish in the centre of the ring.

Spectrum begins as a purified bar of metallic zirconium, an element very similar to titanium in appearance and physical properties. It is light weight, non-toxic, and will never tarnish or corrode.

The ring is precisely machined from the solid bar using a manually controlled lathe and then hand finished using multiple grades of emery and diamond infused lapping paste until the desired finish is achieved. The ring is then oxidised in a precision furnace. Precise control of these variables induces an incredible change to the surface of the metal, converting it into a zirconium dioxide, a ceramic form that happens to be black in appearance.

The ceramic outer layer is extremely durable with a surface hardness equivalent to sapphire. It will resist most daily wear and tear, but if your job involves contact with highly abrasive surfaces such as bricks, concrete and rough metals, we recommend not wearing your ring.

Black zirconium rings can not be resized, and if the ceramic layer is damaged it can not be easily repaired. Please take this into account when choosing your ring.
