Pectolite and Selenite Physical Properties

Pectolite and Selenite Chemical Formula

While comparing Pectolite 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 Pectolite and Selenite chemical formula.

• Chemical formula of Pectolite- Ca 2NaHSi 3O 9Ulrich Henn and Claudio C.
• Chemical formula of Selenite- CaSO4·2H2O

Pectolite and Selenite Specific Gravity

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