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