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