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

Riebeckite and Whitlockite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Riebeckite and Whitlockite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Riebeckite and Whitlockite Optical Properties during the identification of gemstone. Specific gravity of Riebeckite is 3.12 whereas that of Whitlockite is 3.12.
