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

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