While comparing Chrysotile and Allanite 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 Chrysotile and Allanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Chrysotile and Allanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysotile and Allanite Optical Properties during the identification of gemstone. Specific gravity of Chrysotile is 3.40-4.20 whereas that of Allanite is 3.40-4.20.
