Marcasite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Marcasite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Marcasite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Marcasite is 3.1 whereas that of Thulite is 3.1.
