Orthoclase and Moldavite Physical Properties

Orthoclase and Moldavite Chemical Formula

While comparing Orthoclase and Moldavite 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 Moldavite chemical formula.

• Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)

Orthoclase and Moldavite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
