Diaspore and Vanadinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diaspore and Vanadinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Vanadinite Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 6.8-7.1 whereas that of Vanadinite is 6.8-7.1.
