While comparing Herderite and Citrine 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 Herderite and Citrine chemical formula.
Another important criteria for qualitative analysis of gemstones is Herderite and Citrine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Herderite and Citrine Optical Properties during the identification of gemstone. Specific gravity of Herderite is 2.65 whereas that of Citrine is 2.65.
