Variscite and Hibschite Physical Properties

Variscite and Hibschite Chemical Formula

While comparing Variscite and Hibschite 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 Variscite and Hibschite chemical formula.

• Chemical formula of Variscite- AlPO₄ · 2(H₂O)
• Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)

Variscite and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Variscite and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
