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

Pectolite and Anthophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pectolite and Anthophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Anthophyllite Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 2.9-3.5 whereas that of Anthophyllite is 2.9-3.5.
