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

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