Adamite and Friedelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Adamite and Friedelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Friedelite Optical Properties during the identification of gemstone. Specific gravity of Adamite is 3.06-3.19 whereas that of Friedelite is 3.06-3.19.
