Chalcedony and Mellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcedony and Mellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcedony and Mellite Optical Properties during the identification of gemstone. Specific gravity of Chalcedony is 1.58-1.60 whereas that of Mellite is 1.58-1.60.
