Zircon and Goethite Chemical Formula
While comparing Zircon and Goethite 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 Zircon and Goethite chemical formula.

Zircon and Goethite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zircon and Goethite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zircon and Goethite Optical Properties during the identification of gemstone. Specific gravity of Zircon is 4.27-4.29 whereas that of Goethite is 4.27-4.29.
