Hypersthene and Apatite Chemical Formula

While comparing Hypersthene and Apatite 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 Hypersthene and Apatite chemical formula.

Hypersthene and Apatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hypersthene and Apatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hypersthene and Apatite Optical Properties during the identification of gemstone. Specific gravity of Hypersthene is 3.16-3.23 whereas that of Apatite is 3.16-3.23.
