Physical properties

Formation & geological history

Formed under high-pressure, low-temperature metamorphic conditions, typically in serpentinized ultramafic rocks or subduction zone environments. Geological age varies widely depending on the deposit, ranging from Precambrian to Cenozoic.

Uses & applications

Used extensively in fine jewelry, ornamental carvings, spiritual items, and decorative objects.

Geological facts

Jade has been prized in Chinese culture for over 8,000 years, symbolizing purity, virtue, and status. It is remarkably tough and resistant to breaking due to its tightly interwoven micro-fibrous structure.

Field identification & locations

Identified by its high density, cold feel, characteristic fibrous texture under magnification, and resistance to scratching steel (depending on exact mineral type). Found notably in Myanmar, China, Russia, Canada, and Guatemala.
