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

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