Fire Agate and Achroite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fire Agate and Achroite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fire Agate and Achroite Optical Properties during the identification of gemstone. Specific gravity of Fire Agate is 2.90-3.40 whereas that of Achroite is 2.90-3.40.
