Aegirine and Gypsum Chemical Formula
While comparing Aegirine and Gypsum 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 Aegirine and Gypsum chemical formula.

Aegirine and Gypsum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Aegirine and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aegirine and Gypsum Optical Properties during the identification of gemstone. Specific gravity of Aegirine is 2.20-2.40 whereas that of Gypsum is 2.20-2.40.
