Adamite and Riebeckite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Adamite and Riebeckite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Riebeckite Optical Properties during the identification of gemstone. Specific gravity of Adamite is 3.28-3.44 whereas that of Riebeckite is 3.28-3.44.
