While comparing Verdite and Labradorite 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 Verdite and Labradorite chemical formula.
Another important criteria for qualitative analysis of gemstones is Verdite and Labradorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdite and Labradorite Optical Properties during the identification of gemstone. Specific gravity of Verdite is 2.69-2.72 whereas that of Labradorite is 2.69-2.72.
