Andesine and Sphene Chemical Formula
While comparing Andesine 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 Andesine and Sphene chemical formula.

Andesine and Sphene Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Sphene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Sphene Optical Properties during the identification of gemstone. Specific gravity of Andesine is Not Available whereas that of Sphene is Not Available.
