Lepidolite and Pargasite Physical Properties

Lepidolite and Pargasite Chemical Formula

While comparing Lepidolite and Pargasite 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 Lepidolite and Pargasite chemical formula.

• Chemical formula of Lepidolite- Mg 3Si 4O 10(OH) 2Ulrich Henn and Claudio C.
• Chemical formula of Pargasite- NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Lepidolite and Pargasite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lepidolite and Pargasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lepidolite and Pargasite Optical Properties during the identification of gemstone. Specific gravity of Lepidolite is 3.04-3.26 whereas that of Pargasite is 3.04-3.26.
