Peridot and Thomsonite Chemical Formula
While comparing Peridot and Thomsonite 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 Thomsonite chemical formula.
- Chemical formula of Peridot- (Mg,Fe)2SiO4
- Chemical formula of Thomsonite- NaCa 2Al 5Si 5O 20 · 6H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Peridot and Thomsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Peridot and Thomsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Peridot and Thomsonite Optical Properties during the identification of gemstone. Specific gravity of Peridot is 2.25-2.40 whereas that of Thomsonite is 2.25-2.40.
