Fuchsite and Nepheline Physical Properties

Fuchsite and Nepheline Chemical Formula

While comparing Fuchsite and Nepheline 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 Fuchsite and Nepheline chemical formula.

• Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)
• Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.

Fuchsite and Nepheline Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fuchsite and Nepheline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Nepheline Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 2.55-2.65 whereas that of Nepheline is 2.55-2.65.
