Holmquistite and Grossular Physical Properties

Holmquistite and Grossular Chemical Formula

While comparing Holmquistite and Grossular 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 Grossular 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 Grossular- Ca 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Holmquistite and Grossular Specific Gravity

Another important criteria for qualitative analysis of gemstones is Holmquistite and Grossular Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Holmquistite and Grossular Optical Properties during the identification of gemstone. Specific gravity of Holmquistite is 3.55-3.73 whereas that of Grossular is 3.55-3.73.
