Apatite and Agate Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Apatite and Agate Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Agate Opal Optical Properties during the identification of gemstone. Specific gravity of Apatite is 1.98-2.50 whereas that of Agate Opal is 1.98-2.50.
