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

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