Xonotlite and Andradite Chemical Formula
While comparing Xonotlite and Andradite 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 Xonotlite and Andradite chemical formula.

Xonotlite and Andradite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Xonotlite and Andradite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Xonotlite and Andradite Optical Properties during the identification of gemstone. Specific gravity of Xonotlite is 3.70-4.10 whereas that of Andradite is 3.70-4.10.
