Physical properties

Mohs hardness of 6-7, varying shades of green, waxy to vitreous luster, compact microcrystalline structure, and high toughness.

Formed under high-pressure, low-temperature metamorphic conditions in serpentinized ultramafic rocks or subduction zones.

Extensively used in fine jewelry, ornamental carvings, traditional sculptures, and historical weaponry.

Jade has been revered in Chinese culture for over 7,000 years, symbolizing purity, virtue, and status.
