While comparing Tektite and Pectolite 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 Tektite and Pectolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Tektite and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tektite and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Tektite is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
