Linarite and Shigaite Physical Properties

Linarite and Shigaite Chemical Formula

While comparing Linarite 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 Linarite and Shigaite chemical formula.

• Chemical formula of Linarite- PbCu(SO 4)(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Shigaite- Pb6Cu3BiS4

Linarite and Shigaite Specific Gravity

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