Pleonast and Dravite Physical Properties

Pleonast and Dravite Chemical Formula

While comparing Pleonast 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 Pleonast and Dravite chemical formula.

• Chemical formula of Pleonast- MgAl2O4
• Chemical formula of Dravite- Na(Mg 3)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012)

Pleonast and Dravite Specific Gravity

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