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

Goethite and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goethite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goethite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Goethite is 3.00 whereas that of Actinolite is 3.00.
