Oligoclase and Apatite Chemical Formula
While comparing Oligoclase 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 Oligoclase and Apatite chemical formula.

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