While comparing Anthophyllite and Plasma 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 Anthophyllite and Plasma chemical formula.
Another important criteria for qualitative analysis of gemstones is Anthophyllite and Plasma Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Plasma Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is Not Available whereas that of Plasma is Not Available.
