Chiastolite and Sunstone Physical Properties

Chiastolite and Sunstone Chemical Formula

While comparing Chiastolite 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 Chiastolite and Sunstone chemical formula.

• Chemical formula of Chiastolite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth edition (2006)
• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈

Chiastolite and Sunstone Specific Gravity

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