Achroite and Tremolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Achroite and Tremolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Achroite and Tremolite Optical Properties during the identification of gemstone. Specific gravity of Achroite is 2.95-3.07 whereas that of Tremolite is 2.95-3.07.
