Chlorastrolite and Sunstone Physical Properties

Chlorastrolite and Sunstone Chemical Formula

While comparing Chlorastrolite 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 Chlorastrolite and Sunstone chemical formula.

• Chemical formula of Chlorastrolite- Ca 2(Mg,Fe)Al 2(SiO 4)(Si 2O 7)(OH) 2 · H 2O)Arthur Thomas , Gemstones (2009)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Chlorastrolite and Sunstone Specific Gravity

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