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

Spinel and Tantalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spinel and Tantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spinel and Tantalite Optical Properties during the identification of gemstone. Specific gravity of Spinel is 5.2 whereas that of Tantalite is 5.2.
