Riebeckite and Clinohumite Chemical Formula
While comparing Riebeckite and Clinohumite 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 Riebeckite and Clinohumite chemical formula.

Riebeckite and Clinohumite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Riebeckite and Clinohumite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Riebeckite and Clinohumite Optical Properties during the identification of gemstone. Specific gravity of Riebeckite is 3.13-3.75 whereas that of Clinohumite is 3.13-3.75.
