Triplite and Shigaite Physical Properties

Triplite and Shigaite Chemical Formula

While comparing Triplite 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 Triplite and Shigaite chemical formula.

• Chemical formula of Triplite- (Mn2+ ,Fe2+ ,Mg,Ca) 2(PO 4)(F,OH)Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Shigaite- Pb6Cu3BiS4

Triplite and Shigaite Specific Gravity

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