Franklinite and Londonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Franklinite and Londonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Franklinite and Londonite Optical Properties during the identification of gemstone. Specific gravity of Franklinite is 3.34 whereas that of Londonite is 3.34.
