Physical properties
Hardness: 6.5-7.0 (Mohs scale); Color: Pale apple-green to mottled white and emerald; Luster: Greasy to vitreous; Crystal Structure: Monoclinic (granular aggregate); Cleavage: Distinct in two directions; Specific Gravity: 3.25-3.35.
Formation & geological history
Formed in metamorphic rocks under high pressure and low temperature conditions, typically within subduction zones. Most high-quality jadeite is found in serpentinite deposits and relates to Mesozoic geological events.
Uses & applications
Primarily used for high-end jewelry, ornamental carvings (like the Pixiu figure shown), figurines, and luxury decorative objects. It holds significant cultural and investment value in many Asian markets.
Geological facts
Jadeite is much rarer and tougher than Nephrite jade. In Chinese culture, it is often called 'Fei Cui' and is believed to protect the wearer and bring good fortune. The Imperial Jade variety is the most expensive gemstone in the world by weight.
Field identification & locations
Identify in the field by its cold feel, high density (feels heavy for its size), and lack of scratching with a steel knife. It is most famously found in Myanmar (Burma), but also in Guatemala, Russia, and California. Collectors should look for 'glassy' translucent texture and vibrant color consistency.
