Pyrope and Prase Physical Properties

Pyrope and Prase Chemical Formula

While comparing Pyrope and Prase 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 Prase chemical formula.

Pyrope and Prase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Prase Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 2.64-2.69 whereas that of Prase is 2.64-2.69.
