Cerussite and Prase Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cerussite and Prase Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cerussite and Prase Opal Optical Properties during the identification of gemstone. Specific gravity of Cerussite is 1.98-2.25 whereas that of Prase Opal is 1.98-2.25.
