While comparing Gyrolite and Lawsonite 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 Gyrolite and Lawsonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Gyrolite and Lawsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gyrolite and Lawsonite Optical Properties during the identification of gemstone. Specific gravity of Gyrolite is 3.09 whereas that of Lawsonite is 3.09.
