Orthoclase and Lazulite Chemical Formula

While comparing Orthoclase and Lazulite 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 Lazulite chemical formula.

Orthoclase and Lazulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
