Austinite and Linarite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Austinite and Linarite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Linarite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 5.35 whereas that of Linarite is 5.35.
