Zirconium is one of the newest metals to be introduced in the contemporary metals collection. Zirconium is a natural element which begins with a silver color. After the style is milled it is then heat treated. The extreme heat causes oxidation and the ring turns black. The oxidization layer is as hard as sapphire and is there to stay.  Zirconium is the best option on the market if you are looking for a black ring and want to get creative.  Zirconium can be cut with a diamond ring cutter.  Apart from the jewelry industry, Zirconium has military purpose.
