Euclase and Andalusite Chemical Formula
While comparing Euclase and Andalusite 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 Euclase and Andalusite chemical formula.

Euclase and Andalusite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Euclase and Andalusite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Euclase and Andalusite Optical Properties during the identification of gemstone. Specific gravity of Euclase is 3.05-3.21 whereas that of Andalusite is 3.05-3.21.
