Blue spinel and Pyrope Physical Properties

Blue spinel and Pyrope Chemical Formula

While comparing Blue spinel and Pyrope 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 Blue spinel and Pyrope chemical formula.

• Chemical formula of Blue spinel- MgAl2O4
• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Blue spinel and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Blue spinel and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Blue spinel and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Blue spinel is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
