Fuchsite and Oligoclase Chemical Formula

While comparing Fuchsite and Oligoclase 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 Oligoclase chemical formula.

Fuchsite and Oligoclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Fuchsite and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fuchsite and Oligoclase Optical Properties during the identification of gemstone. Specific gravity of Fuchsite is 2.62-2.67 whereas that of Oligoclase is 2.62-2.67.
