About
Your ZiRO ring is made from the mineral Zircon (ZrSi04), which is found is S-type giant stars and the sun. How cool is that? 
When exposed to extreme heat Zirconium forms a black oxidised coasting which feels similar to ceramic in texture. 
The black coating is extremely strong and will never fade. 
And as if that weren't enough, Zirconium is used in nuclear reactors. Which is about as manly as it's possible to get.

As you'd expect, all ZiRO rings come with a lifetime warranty.
