Spinel and Boleite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Boleite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Boleite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 5.05 whereas that of Boleite is 5.05.
