Adamite and Pyromorphite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Adamite and Pyromorphite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Pyromorphite Optical Properties during the identification of gemstone. Specific gravity of Adamite is 6.5-7.1 whereas that of Pyromorphite is 6.5-7.1.
