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