Leucite and Scolecite Chemical Formula
While comparing Leucite and Scolecite 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 Leucite and Scolecite chemical formula.

Leucite and Scolecite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Leucite and Scolecite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Leucite and Scolecite Optical Properties during the identification of gemstone. Specific gravity of Leucite is 2.20-2.23 whereas that of Scolecite is 2.20-2.23.
