Mimetite and Corundum Chemical Formula
While comparing Mimetite and Corundum 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 Mimetite and Corundum chemical formula.

Mimetite and Corundum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Mimetite and Corundum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mimetite and Corundum Optical Properties during the identification of gemstone. Specific gravity of Mimetite is 3.90-4.05 whereas that of Corundum is 3.90-4.05.
