Moldavite and Nepheline Chemical Formula
While comparing Moldavite 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 Moldavite and Nepheline chemical formula.
- Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)
- Chemical formula of Nepheline- Na 3(Na,K)Al 4Si 4O 16Ulrich Henn and Claudio C.
Moldavite and Nepheline Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moldavite and Nepheline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Nepheline Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 2.55-2.65 whereas that of Nepheline is 2.55-2.65.
