Kyanite and Triplite Chemical Formula
While comparing Kyanite and Triplite 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 Kyanite and Triplite chemical formula.

Kyanite and Triplite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Kyanite and Triplite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kyanite and Triplite Optical Properties during the identification of gemstone. Specific gravity of Kyanite is 3.85-3.94 whereas that of Triplite is 3.85-3.94.
