Lazulite and Euclase Chemical Formula

While comparing Lazulite and Euclase 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 Lazulite and Euclase chemical formula.

Lazulite and Euclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazulite and Euclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Euclase Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 3.08-3.12 whereas that of Euclase is 3.08-3.12.
