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