Diaspore and Clinohumite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diaspore and Clinohumite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Clinohumite Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 3.13-3.75 whereas that of Clinohumite is 3.13-3.75.
