While comparing Vesuvianite Idocrase and Pectolite 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 Vesuvianite Idocrase and Pectolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Vesuvianite Idocrase and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vesuvianite Idocrase and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Vesuvianite Idocrase is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
