Agate and Augite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Agate and Augite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Agate and Augite Optical Properties during the identification of gemstone. Specific gravity of Agate is 3.19-3.56 whereas that of Augite is 3.19-3.56.
