Zirconium Zirconium pieces
Zirconium is a hard, silvery grey metal. It is quite reactive, but forms a protective oxide layer in air, which makes it corrosion-resistant. Above all, it is used for special alloys. From cubic zirconia, ZrO2, artificial gemstones can be made, which look very similar to diamonds.
