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

Mellite and Hematite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Mellite and Hematite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mellite and Hematite Optical Properties during the identification of gemstone. Specific gravity of Mellite is 5.00-5.30 whereas that of Hematite is 5.00-5.30.
