Pyrope and Tanzanite Chemical Formula
While comparing Pyrope and Tanzanite 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 Tanzanite chemical formula.

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