Nuummite and Montebrasite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nuummite and Montebrasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nuummite and Montebrasite Optical Properties during the identification of gemstone. Specific gravity of Nuummite is 2.98-3.10 whereas that of Montebrasite is 2.98-3.10.
