Pollucite and Austinite Specific Gravity

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