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

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