Labradorite and Fluorapatite Chemical Formula
While comparing Labradorite and Fluorapatite 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 Labradorite and Fluorapatite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Fluorapatite- Ca 5(PO 4) 3FAnthony et al , Handbook of mineralogy (2001)
Labradorite and Fluorapatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Fluorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Fluorapatite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 3.1-3.25 whereas that of Fluorapatite is 3.1-3.25.
