Material: cubic zirconia/ZrO2
Hardness: 8.50 Mohs
Refractive index: 2.15-2.18
Cubic Zirconia (or CZ) is zirconium oxide (ZrO2 ), is widely synthesized for use as a diamond simulant/imitation and it is a lab made/created stone with a specific gravity of between 5.6-6.00 and at about 8.5 hardness on Mohs scale, which is harder than most natural gemstones. Its refractive index is high at 2.15 – 2.18 (B-G interval) and its luster is very good. Its dispersion is very high at 0.058 – 0.066, exceeding that of diamond (0.044).
Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important competitor for diamonds since commercial production began in 1976.
