Pargasite and Tremolite Chemical Formula
While comparing Pargasite and Tremolite 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 Pargasite and Tremolite chemical formula.

Pargasite and Tremolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pargasite and Tremolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pargasite and Tremolite Optical Properties during the identification of gemstone. Specific gravity of Pargasite is 2.95-3.07 whereas that of Tremolite is 2.95-3.07.
