Hematite and Variscite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hematite and Variscite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Variscite Optical Properties during the identification of gemstone. Specific gravity of Hematite is 2.42-2.58 whereas that of Variscite is 2.42-2.58.
