Linarite and Mottramite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Linarite and Mottramite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Linarite and Mottramite Optical Properties during the identification of gemstone. Specific gravity of Linarite is 5.9 whereas that of Mottramite is 5.9.
