Nuummite and Axinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nuummite and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nuummite and Axinite Optical Properties during the identification of gemstone. Specific gravity of Nuummite is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
