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

Andalusite and Rutile Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andalusite and Rutile Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Rutile Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 4.20-4.30 whereas that of Rutile is 4.20-4.30.
