Wulfenite and Esperite Physical Properties

Wulfenite and Esperite Chemical Formula

While comparing Wulfenite and Esperite 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 Wulfenite and Esperite chemical formula.

• Chemical formula of Wulfenite- PbMoO 4Walter Schumann , Gemstones of the world (2001)
• Chemical formula of Esperite- PbCa 3Zn 4(SiO 4) 4Anthony et al , Handbook of mineralogy (2001)

Wulfenite and Esperite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Wulfenite and Esperite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wulfenite and Esperite Optical Properties during the identification of gemstone. Specific gravity of Wulfenite is 4.28-4.42 whereas that of Esperite is 4.28-4.42.
