Clinohumite and Thulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Clinohumite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Clinohumite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Clinohumite is 3.1 whereas that of Thulite is 3.1.
