Franklinite and Taaffeite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Franklinite and Taaffeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Franklinite and Taaffeite Optical Properties during the identification of gemstone. Specific gravity of Franklinite is 3.60-3.61 whereas that of Taaffeite is 3.60-3.61.
