Bertrandite and Prasiolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Bertrandite and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bertrandite and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Bertrandite is 2.65 whereas that of Prasiolite is 2.65.
