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

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