Zirconia with silver parts "fantasia" bracelet

Zirconia is the artificially synthesized, cubic crystalline form of zirconium (IV) oxide (ZrO2). The material has optical properties that are closer to the characteristics of diamond than any other material. It is not easy for the human eye to distinguish the difference. Zirconia is also popular as imitation diamond. Zirkoniasteen shines a little less than a diamond. On the other hand, this mineral has a larger amount of different colors that sparkle therein (dispersion). There is a difference in hardness and density. Zirconia has a hardness of 8.5 on the Mohs scale. Diamond has hardness 10. Zirconia has a density (specific gravity), which is about 75% greater than that of diamond. As zirconia diamond can be cut into different shapes. The stone is mechanically polished to match the tolerance of diamond cutting.
