Prehnite and Vesuvianite Physical Properties

Prehnite and Vesuvianite Chemical Formula

While comparing Prehnite and Vesuvianite 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 Prehnite and Vesuvianite chemical formula.

• Chemical formula of Prehnite- Ca₂Al₂Si₃O₁₂(OH)
• Chemical formula of Vesuvianite- Ca10(Mg,Fe)2Al4(SiO4)5(Si2O7)2(OH)4

Prehnite and Vesuvianite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Prehnite and Vesuvianite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Vesuvianite Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 3.32-3.43 whereas that of Vesuvianite is 3.32-3.43.
