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