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

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