Sunstone and Leucite Chemical Formula

While comparing Sunstone and Leucite 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 Sunstone and Leucite chemical formula.

Sunstone and Leucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Leucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Leucite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 2.45-2.50 whereas that of Leucite is 2.45-2.50.
