Apatite and Londonite Specific Gravity

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