Apatite and Quartz Chemical Formula

While comparing Apatite and Quartz 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 Apatite and Quartz chemical formula.

Apatite and Quartz Specific Gravity

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