Pyromorphite and Hemimorphite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyromorphite and Hemimorphite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyromorphite and Hemimorphite Optical Properties during the identification of gemstone. Specific gravity of Pyromorphite is 3.30-3.50 whereas that of Hemimorphite is 3.30-3.50.
