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