While comparing Moss Agate and Jet lignite 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 Moss Agate and Jet lignite chemical formula.
Another important criteria for qualitative analysis of gemstones is Moss Agate and Jet lignite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moss Agate and Jet lignite Optical Properties during the identification of gemstone. Specific gravity of Moss Agate is 1.30-1.34 whereas that of Jet lignite is 1.30-1.34.
