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

Diaspore and Realgar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diaspore and Realgar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Realgar Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 3.56 whereas that of Realgar is 3.56.
