  • Chemical formula of Jade- Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6

Andalusite and Jade Specific Gravity

Another important criteria for qualitative analysis of gemstones is Andalusite and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Jade Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 2.90-3.38 whereas that of Jade is 2.90-3.38.
