Axinite and Bytownite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Axinite and Bytownite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Axinite and Bytownite Optical Properties during the identification of gemstone. Specific gravity of Axinite is 2.72-2.75 whereas that of Bytownite is 2.72-2.75.
