Sanidine and Chalcedony Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sanidine and Chalcedony Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sanidine and Chalcedony Optical Properties during the identification of gemstone. Specific gravity of Sanidine is 2.55-2.70 whereas that of Chalcedony is 2.55-2.70.
