Hardystonite and Moldavite Physical Properties

Hardystonite and Moldavite Chemical Formula

While comparing Hardystonite 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 Hardystonite and Moldavite chemical formula.

• Chemical formula of Hardystonite- Ca 2ZnSi 2O 7Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)

Hardystonite and Moldavite Specific Gravity

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