Dravite and Fluorite Physical Properties

Dravite and Fluorite Chemical Formula

While comparing Dravite and Fluorite 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 Fluorite 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 Fluorite- CaF₂

Dravite and Fluorite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dravite and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
