While comparing Aegirine and Prasiolite 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 Prasiolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Aegirine and Prasiolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Aegirine and Prasiolite Optical Properties during the identification of gemstone. Specific gravity of Aegirine is 2.65 whereas that of Prasiolite is 2.65.
