While comparing Spodumene and Povondraite 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 Spodumene and Povondraite chemical formula.
Another important criteria for qualitative analysis of gemstones is Spodumene and Povondraite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spodumene and Povondraite Optical Properties during the identification of gemstone. Specific gravity of Spodumene is 3.26 whereas that of Povondraite is 3.26.
