Diaspore and Lepidolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diaspore and Lepidolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Lepidolite Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 2.80-2.90 whereas that of Lepidolite is 2.80-2.90.
