Hurlbutite and Jet lignite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hurlbutite and Jet lignite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hurlbutite and Jet lignite Optical Properties during the identification of gemstone. Specific gravity of Hurlbutite is 1.30-1.34 whereas that of Jet lignite is 1.30-1.34.
