Pearl and Adamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pearl and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pearl and Adamite Optical Properties during the identification of gemstone. Specific gravity of Pearl is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
