Diaspore and Oligoclase Chemical Formula

While comparing Diaspore 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 Diaspore and Oligoclase chemical formula.

Diaspore and Oligoclase Specific Gravity

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