Melanite and Forsterite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Melanite and Forsterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Melanite and Forsterite Optical Properties during the identification of gemstone. Specific gravity of Melanite is 3.23-3.26 whereas that of Forsterite is 3.23-3.26.
