7 mm wide Flat Grooved Edges Zirconium band.
Zirconium is an element on the periodic table. It has incredible chemical resistance and does not readily react with solvents, acids, bases or other common chemicals. Such unique characteristics make zirconium a great material to use in exotic applications. Traditionally, it used as an alloy in nuclear reactors, submarines, and incendiary munitions.
Our zirconium rings are made using this same high-tech Zirconium alloy, which is comprised primarily of zirconium with a few trace elements. These unique combinations of metals make zirconium rings a perfect option for those with nickel and precious metal allergies and sensitivities.
In its natural state, zirconium is a silver-grey color. It earns its stark black appearance through our proprietary heating process, in which a layer of hard black oxide grows on the metal. This black layer is much harder than raw zirconium, but it is very thin. Unlike oxidized silver and black rhodium, this layer does not rub off over time. It is also more durable than black-coated rings, such as black titanium and black tungsten.
Zirconium is rated as an 8.5 on the Mohs Scale of Hardness.
Zirconium rings are hypoallergenic, lightweight, and comfortable. Zirconium rings should be treated as fine jewelry, and should be removed during harsh activities to avoid scratching.
Cleaning: Zirconium rings need no special care. These rings can be cleaned with regular jewelry cleaner, steam, or ultrasonic
