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

Andalusite and Meionite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andalusite and Meionite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Meionite Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 2.78 whereas that of Meionite is 2.78.
