Montebrasite and Friedelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Montebrasite and Friedelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Friedelite Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 3.06-3.19 whereas that of Friedelite is 3.06-3.19.
