Linarite and Dravite Physical Properties

Linarite and Dravite Chemical Formula

While comparing Linarite 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 Linarite and Dravite chemical formula.

• Chemical formula of Linarite- PbCu(SO 4)(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Dravite- Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Linarite and Dravite Specific Gravity

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