Omphacite and Sunstone Physical Properties

Omphacite and Sunstone Chemical Formula

While comparing Omphacite 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 Omphacite and Sunstone chemical formula.

• Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Omphacite and Sunstone Specific Gravity

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