While comparing Lapis lazuli and Chrysotile 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 Lapis lazuli and Chrysotile chemical formula.
Another important criteria for qualitative analysis of gemstones is Lapis lazuli and Chrysotile Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lapis lazuli and Chrysotile Optical Properties during the identification of gemstone. Specific gravity of Lapis lazuli is 2.51-2.63 whereas that of Chrysotile is 2.51-2.63.
