Willemite and Montebrasite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Willemite and Montebrasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Willemite Vs Montebrasite during the identification of gemstone. Specific gravity of Willemite is whereas that of Montebrasite is .
