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

Idocrase and Axinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Idocrase and Axinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Idocrase and Axinite Optical Properties during the identification of gemstone. Specific gravity of Idocrase is 3.26-3.36 whereas that of Axinite is 3.26-3.36.
