Spinel and Leucite Chemical Formula

While comparing Spinel 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 Spinel and Leucite chemical formula.

Spinel and Leucite Specific Gravity

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