About Black Zirconium

• Blackened through an intense thermal process allowing the graphite black color to go several microns deep.
• This is a superior black finish over black tungsten or titanium as it is not a coating and therefore impossible to rub or scratch off with normal wear.
• The black does not go all the way through the ring making it possible to mill grooves or custom designs letting the steel-gray luster shine through Is approximately 8 on Mohs scale of hardness.
• It cannot break or shatter, however it can dent, but it's extremely difficult to do.
