Antigorite and Leucite Chemical Formula

While comparing Antigorite 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 Antigorite and Leucite chemical formula.

Antigorite and Leucite Specific Gravity

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