Dioptase and Prehnite Physical Properties

Dioptase and Prehnite Chemical Formula

While comparing Dioptase and Prehnite 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 Dioptase and Prehnite chemical formula.

• Chemical formula of Prehnite- Ca₂Al₂Si₃O₁₂(OH)

Dioptase and Prehnite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dioptase and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
