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

Celestine and Spinel Specific Gravity
Another important criteria for qualitative analysis of gemstones is Celestine and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Celestine and Spinel Optical Properties during the identification of gemstone. Specific gravity of Celestine is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
