Spinel and Nephrite Physical Properties

Spinel and Nephrite Chemical Formula

While comparing Spinel and Nephrite 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 Nephrite chemical formula.

Spinel and Nephrite Specific Gravity

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