Feldspar and Elbaite Chemical Formula
While comparing Feldspar and Elbaite 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 Feldspar and Elbaite chemical formula.

Feldspar and Elbaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Feldspar and Elbaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Feldspar and Elbaite Optical Properties during the identification of gemstone. Specific gravity of Feldspar is 2.90-3.10 whereas that of Elbaite is 2.90-3.10.
