Physical properties

Formation & geological history

Formed by metamorphism and metasomatism in tectonically active zones, commonly in serpentinite-associated rocks; jade deposits range from Paleozoic to Cenozoic in age.

Uses & applications

Carved into bangles, ornaments, tools, and sculptures; valued in jewelry and cultural art, while unsuitable for ordinary construction use.

Geological facts

The image shows a polished, carved bangle rather than a raw specimen. Nephrite’s exceptional toughness comes from densely interwoven amphibole fibers, making it difficult to break despite moderate hardness.

Field identification & locations

Common sources include Myanmar, China, Guatemala, New Zealand, Canada, Russia, and Wyoming; identify with refractive index, specific gravity, microscopic texture, and gemological testing, since green serpentine and dyed materials can resemble jade.
