Physical properties
Hardness: 6.5 to 7 on the Mohs scale, Color: Pale to deep lavender or violet, Luster: Vitreous to greasy, Crystal Structure: Monoclinic, Cleavage: Poor, Specific Gravity: 3.24 to 3.43
Formation & geological history
Formed under high-pressure, low-temperature metamorphic conditions in subduction zones, typically within serpentinite mélanges.
Uses & applications
Used primarily in fine jewelry, such as carved pendants, beaded bracelets, and rings, as well as ornamental sculptures.
Geological facts
Lavender jadeite, often called 'Fei Cui' in Chinese, gets its purple color from trace amounts of manganese incorporated into the pyroxene crystal structure.
Field identification & locations
Highly prized in Asian markets, particularly in China and Myanmar; identification involves checking specific gravity, toughness, and microscopic fibrous interlocking crystal structures.
