Sphene and Dravite Physical Properties

Sphene and Dravite Chemical Formula

While comparing Sphene and Dravite 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 Sphene and Dravite chemical formula.

• Chemical formula of Sphene- CaTiSiO5
• Chemical formula of Dravite- Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Sphene and Dravite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sphene and Dravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphene and Dravite Optical Properties during the identification of gemstone. Specific gravity of Sphene is 3.03-3.18 whereas that of Dravite is 3.03-3.18.
