Prase and Shigaite Physical Properties

Prase and Shigaite Chemical Formula

While comparing Prase and Shigaite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Prase and Shigaite chemical formula.

• Chemical formula of Prase- SiO 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Shigaite- Pb6Cu3BiS4

Prase and Shigaite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Prase and Shigaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prase and Shigaite Optical Properties during the identification of gemstone. Specific gravity of Prase is 2.32 whereas that of Shigaite is 2.32.
