Selenite and Wulfenite Physical Properties

Selenite and Wulfenite Chemical Formula

While comparing Selenite and Wulfenite 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 Wulfenite chemical formula.

• Chemical formula of Wulfenite- PbMoO 4Walter Schumann , Gemstones of the world (2001)

Selenite and Wulfenite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Selenite and Wulfenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Selenite and Wulfenite Optical Properties during the identification of gemstone. Specific gravity of Selenite is 6.50-7.00 whereas that of Wulfenite is 6.50-7.00.
