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