While comparing Scolecite and Smaragdite 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 Scolecite and Smaragdite chemical formula.
Another important criteria for qualitative analysis of gemstones is Scolecite and Smaragdite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scolecite and Smaragdite Optical Properties during the identification of gemstone. Specific gravity of Scolecite is 3.24-3.50 whereas that of Smaragdite is 3.24-3.50.
