Peridot and Triplite Chemical Formula
While comparing Peridot and Triplite 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 Peridot and Triplite chemical formula.
- Chemical formula of Peridot- (Mg,Fe)2SiO4
- Chemical formula of Triplite- (Mn2+ ,Fe2+ ,Mg,Ca) 2(PO 4)(F,OH)Michael OâDonoghue , Gems, Sixth Edition (2006)
Peridot and Triplite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Peridot and Triplite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Peridot and Triplite Optical Properties during the identification of gemstone. Specific gravity of Peridot is 3.85-3.94 whereas that of Triplite is 3.85-3.94.
