Fayalite and Antigorite Chemical Formula
While comparing Fayalite and Antigorite 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 Fayalite and Antigorite chemical formula.

Fayalite and Antigorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fayalite and Antigorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fayalite and Antigorite Optical Properties during the identification of gemstone. Specific gravity of Fayalite is 2.58-2.80 whereas that of Antigorite is 2.58-2.80.
