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