Selenite and Meionite Physical Properties

Selenite and Meionite Chemical Formula

While comparing Selenite and Meionite 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 Selenite and Meionite chemical formula.

• Chemical formula of Selenite- CaSO4·2H2O
• Chemical formula of Meionite- 3CaAl 2Si 2O 8 · CaCO 3Anthony et al , Handbook of mineralogy (2001)

Selenite and Meionite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Selenite and Meionite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Selenite and Meionite Optical Properties during the identification of gemstone. Specific gravity of Selenite is 2.78 whereas that of Meionite is 2.78.
