Shigaite and Omphacite Physical Properties

Shigaite and Omphacite Chemical Formula

While comparing Shigaite and Omphacite 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 Shigaite and Omphacite chemical formula.

• Chemical formula of Shigaite- Pb6Cu3BiS4
• Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)

Shigaite and Omphacite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Shigaite and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shigaite and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Shigaite is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
