Lepidolite and Williamsite Physical Properties

Lepidolite and Williamsite Chemical Formula

While comparing Lepidolite and Williamsite 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 Williamsite chemical formula.

• Chemical formula of Lepidolite- Mg 3Si 4O 10(OH) 2Ulrich Henn and Claudio C.
• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Lepidolite and Williamsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lepidolite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lepidolite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Lepidolite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
