Beryllonite and Langbeinite Chemical Formula
While comparing Beryllonite and Langbeinite 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 Beryllonite and Langbeinite chemical formula.

Beryllonite and Langbeinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Beryllonite and Langbeinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Beryllonite and Langbeinite Optical Properties during the identification of gemstone. Specific gravity of Beryllonite is Not Available whereas that of Langbeinite is Not Available.
