While comparing Prasiolite and Leucite 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 Prasiolite and Leucite chemical formula.
Another important criteria for qualitative analysis of gemstones is Prasiolite and Leucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prasiolite and Leucite Optical Properties during the identification of gemstone. Specific gravity of Prasiolite is 2.45-2.50 whereas that of Leucite is 2.45-2.50.
