Eudialyte and Gahnite Chemical Formula
While comparing Eudialyte and Gahnite 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 Eudialyte and Gahnite chemical formula.

Eudialyte and Gahnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Eudialyte and Gahnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eudialyte and Gahnite Optical Properties during the identification of gemstone. Specific gravity of Eudialyte is 4.00-4.62 whereas that of Gahnite is 4.00-4.62.
