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