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

Omphacite and Phenakite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Omphacite and Phenakite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Phenakite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.90-2.98 whereas that of Phenakite is 2.90-2.98.
