Montebrasite and Triplite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Montebrasite and Triplite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Triplite Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 3.85-3.94 whereas that of Triplite is 3.85-3.94.
