While comparing Hyalite and Moss Agate 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 Hyalite and Moss Agate chemical formula.
Another important criteria for qualitative analysis of gemstones is Hyalite and Moss Agate Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Moss Agate Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 2.58-2.64 whereas that of Moss Agate is 2.58-2.64.
