Physical properties

Hardness of 6.5 to 7 on the Mohs scale, varying shades of green, white, and orange, vitreous to greasy luster, monoclinic crystal system, and a specific gravity of 3.2 to 3.4.

Formation & geological history

Formed under high-pressure, low-temperature metamorphic conditions in serpentinite convergence zones, often taking millions of years in subduction zone environments.

Uses & applications

Prized globally for high-end jewelry, intricate ornamental carvings, and decorative sculptures.

Geological facts

Jadeite was historically valued more than gold in Mesoamerican civilizations like the Olmecs and Mayas. It has a tough interlocking microcrystalline structure that makes it extremely resistant to breaking.

Field identification & locations

Identify by its dense feel, uneven fracture, and resistance to scratching by steel. Commonly sourced from Myanmar, Guatemala, and California.
