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

Tantalite and Glaucophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tantalite and Glaucophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tantalite and Glaucophane Optical Properties during the identification of gemstone. Specific gravity of Tantalite is 3-3.15 whereas that of Glaucophane is 3-3.15.
