Richterite and Selenite Physical Properties

Richterite and Selenite Chemical Formula

While comparing Richterite and Selenite 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 Richterite and Selenite chemical formula.

• Chemical formula of Richterite- Na(CaNa)(Mg,Fe++)5(Si8O22)(OH)2
• Chemical formula of Selenite- CaSO4·2H2O

Richterite and Selenite Specific Gravity

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