Formation & geological history
Formed under high-pressure, low-temperature metamorphic conditions in subduction zones; primary deposits are many millions of years old.
Uses & applications
Extensively used in jewelry (rings, bangles, pendants), ornamental carvings, and historical talismans for luck and health.
Geological facts
While emerald green is the most famous, yellow jade is prized for its rarity and its association with fire energy and the solar plexus chakra in traditional lore.
