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

Antigorite and Sugilite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Antigorite and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Antigorite and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Antigorite is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
