Orthoclase and Nuummite Chemical Formula
While comparing Orthoclase and Nuummite 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 Orthoclase and Nuummite chemical formula.

Orthoclase and Nuummite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Orthoclase and Nuummite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Nuummite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 3.18-3.37 whereas that of Nuummite is 3.18-3.37.
