Black Zirconium

Strong, distinctive and as black as a magpie in a mineshaft.

• High strength-to-weight ratio: Zirconium is lightweight but strong, making it comfortable for daily wear without compromising toughness.

• Corrosion-resistant: It resists corrosion from water, sweat, and most chemicals, making it ideal for long-term wear.

• Hypoallergenic: It’s biocompatible, meaning it’s safe for those with skin sensitivities.

• Moderately scratch-resistant: While zirconium is harder than silver, gold, and platinum, it’s not as scratch-resistant as materials like tungsten or ceramic.

• The black finish on zirconium rings is created by heat-treating the metal, forming a zirconium oxide layer. This oxidized surface is harder than raw zirconium but can still show scratches with heavy or abrasive use.
  

ZiRO rings are supremely comfortable, hypoallergenic and available in a range of unique, modern and classic styles. 

ZiRO 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.
