Montebrasite and Hauyne Specific Gravity

Another important criteria for qualitative analysis of gemstones is Montebrasite and Hauyne Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Hauyne Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 2.4-2.5 whereas that of Hauyne is 2.4-2.5.
