Formation & geological history

Formed in metamorphic environments under high pressure and relatively low temperature conditions, typically in serpentinite convergence zones.

Uses & applications

Used primarily in fine jewelry, carvings, ornaments, and historical artifacts due to its toughness and aesthetic appeal.

Geological facts

Jadeite is one of the two minerals recognized as jade (the other being nephrite). It has exceptional toughness, making it harder to break than diamond despite its lower scratch hardness.

Field identification & locations

Found in places like Myanmar (Burma), Guatemala, Russia, and California. Identified in the field by its high density, microcrystalline texture, and toughness.
