  • Chemical formula of Prase- SiO 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Sapphire and Prase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sapphire and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Prase Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.64-2.69 whereas that of Prase is 2.64-2.69.
