Physical properties

Hardness: 6-7 (Mohs); Color: Milky white to translucent white; Luster: Greasy to vitreous; Crystal structure: Monoclinic; Cleavage: None/splintery; Specific gravity: 2.9-3.3

Formation & geological history

Formed under high pressure and low temperature metamorphic conditions, typically in subduction zones or along fault lines involving serpentinite and dolomitic marble.

Uses & applications

Primarily used for high-end jewelry, beadwork, ornamental carvings, and historical artifacts. Highly valued in Asian cultures as a symbol of purity and longevity.

Geological facts

White jade is often referred to as 'Mutton Fat Jade' when it has a specific creamy, translucent quality. It is tougher than steel due to its interlocking fibrous structure, making it incredibly resistant to fracture.

Field identification & locations

Identify by its characteristic 'greasy' feel and high toughness. In the field, look for smooth, water-worn boulders in riverbeds in regions like Xinjiang (China), Myanmar, or British Columbia. Natural white jade should feel cold to the touch.
