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

Goethite and Kunzite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goethite and Kunzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goethite and Kunzite Optical Properties during the identification of gemstone. Specific gravity of Goethite is 3.15-3.21 whereas that of Kunzite is 3.15-3.21.
