Physical properties
Hardness: 6.5-7.0 (Mohs scale), Color: Pale green to translucent white (mutton fat), Luster: Vitreous to greasy, Crystal structure: Monoclinic, Cleavage: Two directions at 90 degrees (though rarely visible in beads), Specific gravity: 3.25-3.36
Formation & geological history
Formed in high-pressure, low-temperature metamorphic environments, typically in subduction zones where oceanic plates meet continental plates. Associated with serpentinite rocks.
Uses & applications
Primarily used in jewelry (beads, bangles, pendants), ornamental carvings, and historical artifacts. Highly valued in East Asian cultures for spiritual and status reasons.
Geological facts
There are two distinct minerals called Jade: Jadeite and Nephrite. Jadeite is the rarer and harder of the two. Historically, it was known as the 'Stone of Heaven' in China.
Field identification & locations
Identify by its cool feel to the touch, high density (feels heavy for its size), and bell-like ring when struck with something hard. Common sources include Myanmar (Burma), Guatemala, and Russia.
