While comparing Citrine and Monazite 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 Citrine and Monazite chemical formula.
Another important criteria for qualitative analysis of gemstones is Citrine and Monazite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Citrine and Monazite Optical Properties during the identification of gemstone. Specific gravity of Citrine is 4.80-5.50 whereas that of Monazite is 4.80-5.50.
