Dravite and Magnetite Chemical Formula
While comparing Dravite and Magnetite 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 Dravite and Magnetite chemical formula.

Dravite and Magnetite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Magnetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Magnetite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 5.2 whereas that of Magnetite is 5.2.
