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

Pectolite and Caledonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pectolite and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
