Meionite and Spinel Chemical Formula
While comparing Meionite and Spinel 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 Meionite and Spinel chemical formula.

Meionite and Spinel Specific Gravity
Another important criteria for qualitative analysis of gemstones is Meionite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Meionite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Meionite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
