Andradite and Wernerite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andradite and Wernerite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andradite and Wernerite Optical Properties during the identification of gemstone. Specific gravity of Andradite is 2.50-2.80 whereas that of Wernerite is 2.50-2.80.
