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

Fluorite and Oligoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorite and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorite and Oligoclase Optical Properties during the identification of gemstone. Specific gravity of Fluorite is 2.62-2.67 whereas that of Oligoclase is 2.62-2.67.
