Physical properties
Hardness: 6.5-7.0 (Mohs), Color: Pale green to mottled white/tan, Luster: Greasy to vitreous, Crystal Structure: Monoclinic, Specific Gravity: 3.2-3.4
Formation & geological history
Formed under high pressure and low temperature conditions in subduction zones. This water-worn pebble likely originated from metamorphic rocks such as serpentinite or greenschist.
Uses & applications
Primarily used in jewelry, ornamental carvings, and talismans. Highly valued in many cultures for its durability and aesthetic appeal.
Geological facts
Jade is actually a term used for two different minerals: Jadeite and Nephrite. Jadeite is the rarer and harder of the two. It is known as the 'Stone of Heaven' in Chinese culture.
Field identification & locations
Identified in the field by its extreme toughness, high density, and smooth, waxy surface when wet. Common in riverbeds in serpentinite-bearing regions like California, Myanmar, and New Zealand.
