While comparing Grossular Garnet and Ulexite 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 Grossular Garnet and Ulexite chemical formula.
Another important criteria for qualitative analysis of gemstones is Grossular Garnet and Ulexite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Grossular Garnet and Ulexite Optical Properties during the identification of gemstone. Specific gravity of Grossular Garnet is 1.65-1.99 whereas that of Ulexite is 1.65-1.99.
