Riebeckite and Serandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Riebeckite and Serandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Riebeckite and Serandite Optical Properties during the identification of gemstone. Specific gravity of Riebeckite is 3.52 whereas that of Serandite is 3.52.
