Friedelite and Marialite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Friedelite and Marialite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Friedelite and Marialite Optical Properties during the identification of gemstone. Specific gravity of Friedelite is 2.50 whereas that of Marialite is 2.50.
