Londonite and Antigorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Londonite and Antigorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Londonite and Antigorite Optical Properties during the identification of gemstone. Specific gravity of Londonite is 2.58-2.80 whereas that of Antigorite is 2.58-2.80.
