Tremolite and Ettringite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tremolite and Ettringite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tremolite and Ettringite Optical Properties during the identification of gemstone. Specific gravity of Tremolite is 1.77 whereas that of Ettringite is 1.77.
