Grossular and Sphene Physical Properties

Grossular and Sphene Chemical Formula

While comparing Grossular and Sphene 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 Grossular and Sphene chemical formula.

• Chemical formula of Grossular- Ca 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Sphene- CaTiSiO5

Grossular and Sphene Specific Gravity

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