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

Moldavite and Pyrope Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moldavite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
