Hematite and Tugtupite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hematite and Tugtupite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Tugtupite Optical Properties during the identification of gemstone. Specific gravity of Hematite is 2.30-2.60 whereas that of Tugtupite is 2.30-2.60.
