Holmquistite and Sodalite Physical Properties

Holmquistite and Sodalite Chemical Formula

While comparing Holmquistite and Sodalite 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 Holmquistite and Sodalite chemical formula.

• Chemical formula of Holmquistite- Li 2[(Mg,Fe2+ ) 3Al 2]Si 8O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Sodalite- Na₈Al₆Si₆O₂₄Cl₂

Holmquistite and Sodalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Holmquistite and Sodalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Holmquistite and Sodalite Optical Properties during the identification of gemstone. Specific gravity of Holmquistite is 2.15-2.40 whereas that of Sodalite is 2.15-2.40.
