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

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