Apatite and Brazilianite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apatite and Brazilianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Brazilianite Optical Properties during the identification of gemstone. Specific gravity of Apatite is 2.98-2.99 whereas that of Brazilianite is 2.98-2.99.
