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

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