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

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