Lazulite and Selenite Physical Properties

Lazulite and Selenite Chemical Formula

While comparing Lazulite 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 Lazulite and Selenite chemical formula.

• Chemical formula of Lazulite- (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references
• Chemical formula of Selenite- CaSO4·2H2O

Lazulite and Selenite Specific Gravity

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