Sunstone and Colemanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sunstone and Colemanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Colemanite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.40-2.42 whereas that of Colemanite is 2.40-2.42.
