Physical properties
Mohs hardness of 6.5 to 7; typically green, white, or lavender; vitreous to greasy luster; monoclinic crystal system; specific gravity of 3.25 to 3.43
Formation & geological history
Formed under high-pressure, low-temperature metamorphic conditions in subduction zones, typically within serpentinite mélanges.
Uses & applications
Widely used for high-end jewelry, carved ornaments, beads, and decorative items due to its toughness and beauty.
Geological facts
Jadeite is one of two minerals recognized as jade (the other being nephrite). It is exceptionally tough due to its microcrystalline interlocking fibrous structure.
Field identification & locations
Can be identified by its high density (feels heavy for its size), toughness, and characteristic fibrous texture under magnification. Commonly sourced from Myanmar, Guatemala, and California.
