Pyrope and Selenite Physical Properties

Pyrope and Selenite Chemical Formula

While comparing Pyrope 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 Pyrope and Selenite chemical formula.

• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Selenite- CaSO4·2H2O

Pyrope and Selenite Specific Gravity

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