Shigaite and Agate Specific Gravity

Another important criteria for qualitative analysis of gemstones is Shigaite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shigaite and Agate Optical Properties during the identification of gemstone. Specific gravity of Shigaite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
