Chlorastrolite and Selenite Physical Properties

Chlorastrolite and Selenite Chemical Formula

While comparing Chlorastrolite 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 Chlorastrolite and Selenite chemical formula.

• Chemical formula of Chlorastrolite- Ca 2(Mg,Fe)Al 2(SiO 4)(Si 2O 7)(OH) 2 · H 2O)Arthur Thomas , Gemstones (2009)
• Chemical formula of Selenite- CaSO4·2H2O

Chlorastrolite and Selenite Specific Gravity

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