Fluorite and Coral Chemical Formula
While comparing Fluorite and Coral 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 Fluorite and Coral chemical formula.

Fluorite and Coral Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorite and Coral Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorite and Coral Optical Properties during the identification of gemstone. Specific gravity of Fluorite is 2.60-2.70 whereas that of Coral is 2.60-2.70.
