Parisite and Gypsum Physical Properties

Parisite and Gypsum Chemical Formula

While comparing Parisite and Gypsum 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 Parisite and Gypsum chemical formula.

• Chemical formula of Parisite- Ca(Nd,Ce,La) 2(CO 3) 3F 2Ulrich Henn and Claudio C.
• Chemical formula of Gypsum- CaSO 4 -2(H 2O)Arthur Thomas , Gemstones (2009)

Parisite and Gypsum Specific Gravity

Another important criteria for qualitative analysis of gemstones is Parisite and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Parisite and Gypsum Optical Properties during the identification of gemstone. Specific gravity of Parisite is 2.20-2.40 whereas that of Gypsum is 2.20-2.40.
