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

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