Pyrope and Dioptase Physical Properties

Pyrope and Dioptase Chemical Formula

While comparing Pyrope and Dioptase 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 Dioptase chemical formula.

Pyrope and Dioptase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Dioptase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Dioptase Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 3.25-3.35 whereas that of Dioptase is 3.25-3.35.
