0.8~ 15Mm factory pink ruby loose stone wholesale round colored zircon, artificial gemstone semi-precious stone

White zircon can withstand high temperatures of 1800 ° C
Colored zircon is not resistant to high temperatures and will change color beyond 600 ° C
The larger the size of the colored zircon, the darker the color, and the smaller the size, the lighter the color.

 White zircon heat resistance 1200~ 1500 degrees Celsius

Color zircon heat resistance 600~ 700 degrees Celsius

Synthetic ruby, synthetic spinel heat resistant 1800 degrees Celsius

Main purpose:Jewelry Inlay, Jewelry DIY

Dispersion:The dispersion of cubic zirconia is 0.060, higher than that of diamond 0.044.

Therefore, cubic zirconia is not more brilliant than diamonds.
Hardness:Mohs hardness of cubic zirconia is 8.5, diamond is 10.

Defect:Cubic zirconia is basically flawless inside and out,

Natural diamonds are rarely flawless inside and out

Refractive Index:Cubic zirconia has a refractive index of 2.176, slightly lower than diamond's 2.417.

Cut:Due to the different refractive indices, the cut of cubic zirconia will be slightly different from that of diamonds

Careful observation under magnifying glass can be found
