About Cubic Zirconia
Cubic zirconia (CZ) is a synthesized crystalline form of zirconium oxide that is the most popular and widely used diamond simulant in the world, prized for its excellent hardness, high refractive index, and strong dispersion—creating impressive diamond-like brilliance at a tiny fraction of diamond's cost. First developed for industrial use by Soviet scientists and introduced commercially in 1976, it can be produced in virtually any color. Though an entirely synthetic material, CZ revolutionized affordable gemstone jewelry.
