Albite and Carnelian Specific Gravity
Another important criteria for qualitative analysis of gemstones is Albite and Carnelian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Albite and Carnelian Optical Properties during the identification of gemstone. Specific gravity of Albite is 2.58-2.64 whereas that of Carnelian is 2.58-2.64.
