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

Spinel and Crocoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Crocoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Crocoite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 5.90-6.10 whereas that of Crocoite is 5.90-6.10.
