While comparing Unakite and Anthophyllite 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 Unakite and Anthophyllite chemical formula.
Another important criteria for qualitative analysis of gemstones is Unakite and Anthophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Unakite and Anthophyllite Optical Properties during the identification of gemstone. Specific gravity of Unakite is 2.9-3.5 whereas that of Anthophyllite is 2.9-3.5.
