Shigaite and Chrysoprase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Shigaite and Chrysoprase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shigaite and Chrysoprase Optical Properties during the identification of gemstone. Specific gravity of Shigaite is 2.58-2.64 whereas that of Chrysoprase is 2.58-2.64.
