While comparing Stolzite and Geodes 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 Stolzite and Geodes chemical formula.
Another important criteria for qualitative analysis of gemstones is Stolzite and Geodes Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stolzite and Geodes Optical Properties during the identification of gemstone. Specific gravity of Stolzite is Not Available whereas that of Geodes is Not Available.
