Moonstone and Oligoclase Chemical Formula
While comparing Moonstone 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 Moonstone and Oligoclase chemical formula.

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