Pyrope and Prehnite Physical Properties

Pyrope and Prehnite Chemical Formula

While comparing Pyrope 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 Pyrope and Prehnite chemical formula.

• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Prehnite- Ca₂Al₂Si₃O₁₂(OH)

Pyrope and Prehnite Specific Gravity

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