Melanite and Jet Specific Gravity
Another important criteria for qualitative analysis of gemstones is Melanite and Jet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Melanite and Jet Optical Properties during the identification of gemstone. Specific gravity of Melanite is 1.19-1.35 whereas that of Jet is 1.19-1.35.
