Seraphinite and Shigaite Physical Properties

Seraphinite and Shigaite Chemical Formula

While comparing Seraphinite 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 Seraphinite and Shigaite chemical formula.

• Chemical formula of Seraphinite- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Shigaite- Pb6Cu3BiS4

Seraphinite and Shigaite Specific Gravity

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