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

Orthoclase and Opal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Orthoclase and Opal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Opal Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 1.98-2.25 whereas that of Opal is 1.98-2.25.
