Erythrite and Celestine Chemical Formula
While comparing Erythrite and Celestine 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 Erythrite and Celestine chemical formula.

Erythrite and Celestine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Erythrite and Celestine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Erythrite and Celestine Optical Properties during the identification of gemstone. Specific gravity of Erythrite is 3.90-4.00 whereas that of Celestine is 3.90-4.00.
