Labradorite and Steatite Chemical Formula
While comparing Labradorite and Steatite 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 Steatite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)
Labradorite and Steatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Steatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Steatite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.20-2.80 whereas that of Steatite is 2.20-2.80.
