Xenotime and Austinite Specific Gravity

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