Adamite and Morganite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Adamite and Morganite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Morganite Optical Properties during the identification of gemstone. Specific gravity of Adamite is 2.71-2.90 whereas that of Morganite is 2.71-2.90.
