Lazulite and Steatite Physical Properties

Lazulite and Steatite Chemical Formula

While comparing Lazulite 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 Lazulite and Steatite chemical formula.

• Chemical formula of Lazulite- (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references
• Chemical formula of Steatite- Mg 3Si 4O 10(OH) 2Gemdat.org , Management Team (2012)

Lazulite and Steatite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazulite and Steatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Steatite Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 2.20-2.80 whereas that of Steatite is 2.20-2.80.
