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

Magnesite and Agate Specific Gravity
Another important criteria for qualitative analysis of gemstones is Magnesite and Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Magnesite and Agate Optical Properties during the identification of gemstone. Specific gravity of Magnesite is 2.60-2.64 whereas that of Agate is 2.60-2.64.
