Pyrope and Epidote Physical Properties

Pyrope and Epidote Chemical Formula

While comparing Pyrope and Epidote 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 Epidote chemical formula.

Pyrope and Epidote Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Epidote Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Epidote Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 3.25-3.50 whereas that of Epidote is 3.25-3.50.
