Hurlbutite and Annabergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hurlbutite and Annabergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hurlbutite and Annabergite Optical Properties during the identification of gemstone. Specific gravity of Hurlbutite is 3.07 whereas that of Annabergite is 3.07.
