Physical properties
Hardness: 6.5-7 on the Mohs scale, Color: Pale green, emerald green, white, or mottled, Luster: Vitreous to pearly, Crystal Structure: Monoclinic, Cleavage: Good in two directions, Specific Gravity: 3.24-3.43
Formation & geological history
Formed under high-pressure, low-temperature metamorphic conditions in serpentinite-bearing subduction zones, often taking millions of years to crystallize.
Uses & applications
Used primarily in high-end jewelry, carving, ornamental objects, and as a historical status symbol in various cultures.
Geological facts
Jadeite was treasured by the ancient Maya, Olmecs, and Chinese dynasties, often holding more value than gold. It is one of the two distinct minerals recognized as jade, the other being nephrite.
Field identification & locations
Can be identified in the field by its high density (feels heavy for its size), tough interlocking fibrous structure, and characteristic green color. Commonly found in Myanmar, Guatemala, and California.
