Axinite and Austinite Specific Gravity

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