100pcs AAAAA Grade White 4-12mm Loose Zircon Stone Round Cut Cubic Zirconia

CZ Stone Heat resistance:
White zircon heat resistance 1200 ~ 1500 ℃
Color zircon heat resistance 600 ~ 700 degrees Celsius
Synthetic ruby, synthetic spinel, heat resistance 1800 ℃

Main uses: Jewelry inlay, jewelry DIY
Dispersion: the dispersion of cubic zirconia is 0.060, which is higher than 0.044 of diamond
Therefore, cubic zirconia is not more brilliant than diamond.
Hardness: Cubic Zirconia Mohs hardness 8.5, diamond 10
Defects: cubic zirconia is basically perfect inside and outside the market,
Natural diamonds are rarely flawless inside and outside
Refractive index: the refractive index of cubic zirconia is 2.176, slightly lower than that of diamond
Cutting: due to different refractive index, the cutting of cubic zirconia is slightly different from that of diamond
It can be found by careful observation under a magnifying glass
