While comparing Lamprophyre and Anhydrite 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 Lamprophyre and Anhydrite chemical formula.
Another important criteria for qualitative analysis of gemstones is Lamprophyre and Anhydrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lamprophyre and Anhydrite Optical Properties during the identification of gemstone. Specific gravity of Lamprophyre is 2.90-2.98 whereas that of Anhydrite is 2.90-2.98.
