Linarite and Fluorite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Linarite and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Linarite and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Linarite is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
