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

Pectolite and Leucite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pectolite and Leucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pectolite and Leucite Optical Properties during the identification of gemstone. Specific gravity of Pectolite is 2.45-2.50 whereas that of Leucite is 2.45-2.50.
