Moldavite and Sunstone Physical Properties

Moldavite and Sunstone Chemical Formula

While comparing Moldavite and Sunstone 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 Moldavite and Sunstone chemical formula.

• Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Moldavite and Sunstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Moldavite and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
