Axinite and Erythrite Chemical Formula
While comparing Axinite and Erythrite 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 Axinite and Erythrite chemical formula.

Axinite and Erythrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Axinite and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Axinite and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Axinite is 3.06 whereas that of Erythrite is 3.06.
