Anthophyllite and Andesine Chemical Formula
While comparing Anthophyllite and Andesine 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 Anthophyllite and Andesine chemical formula.

Anthophyllite and Andesine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anthophyllite and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Andesine Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
