Dravite and Bornite Physical Properties

Dravite and Bornite Chemical Formula

While comparing Dravite and Bornite 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 Dravite and Bornite chemical formula.

• Chemical formula of Dravite- Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)
• Chemical formula of Bornite- Cu5FeS4

Dravite and Bornite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dravite and Bornite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Bornite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 5.06-5.08 whereas that of Bornite is 5.06-5.08.
