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

Moldavite and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moldavite and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
