Oligoclase and Moissanite Chemical Formula

While comparing Oligoclase and Moissanite 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 Oligoclase and Moissanite chemical formula.

Oligoclase and Moissanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Moissanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Moissanite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 3.17-3.24 whereas that of Moissanite is 3.17-3.24.
