Jadeite (Jade)

Physical Properties

Hardness: 6.5–7.0 (Mohs scale); Color: Typically Apple-green, emerald-green, or lavender; Luster: Vitreous to greasy; Crystal Structure: Monoclinic; Cleavage: Good (rarely seen); Specific Gravity: 3.25–3.36.

Formation & Geological History

Formed in metamorphic rocks under high pressure and low temperature conditions, typically within subduction zones. Found in Burma, Guatemala, Japan, and California.

Uses & Applications

Predominantly used for high-end jewelry (rings, pendants, bangles) and cultural carvings/artifacts. It is highly valued for its toughness and aesthetic bloom.

Geological Facts

Jade has been used for over 5,000 years, originally for axe heads due to its extreme toughness before becoming a symbol of status and imperial power in China.

Field Identification & Locations

Identify in the field by its high density (feels heavy for its size), extreme toughness (difficult to break), and cold touch. It often has a unique 'mottled' texture under magnification.
