Carnelian and Franklinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Carnelian and Franklinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Carnelian and Franklinite Optical Properties during the identification of gemstone. Specific gravity of Carnelian is 5.05-5.22 whereas that of Franklinite is 5.05-5.22.
