Pezzottaite and Austinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pezzottaite and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pezzottaite and Austinite Optical Properties during the identification of gemstone. Specific gravity of Pezzottaite is 4.12 whereas that of Austinite is 4.12.
