Selenite and Tinzenite Physical Properties

Selenite and Tinzenite Chemical Formula

While comparing Selenite and Tinzenite 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 Tinzenite chemical formula.

• Chemical formula of Selenite- CaSO4·2H2O
• Chemical formula of Tinzenite- (Ca,Mn2+ ,Fe2+ ) 3Al 2BSi 4O 15(OH)Anthony et al , Handbook of mineralogy (2001)

Selenite and Tinzenite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Selenite and Tinzenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Selenite and Tinzenite Optical Properties during the identification of gemstone. Specific gravity of Selenite is 3.355-3.433 whereas that of Tinzenite is 3.355-3.433.
