Jadeite

Physical Properties

Hardness: 6.5–7.0 Mohs; Color: Apple-green, emerald-green, white, lavender; Luster: Vitreous to greasy; Crystal Structure: Monoclinic; Specific Gravity: 3.25–3.35.

Formation & Geological History

Formed in metamorphic rocks under high pressure and low temperature conditions, typically in subduction zones. It is often found in serpentinites and occurs as masses of interlocking microcrystals.

Uses & Applications

Predominantly used for fine jewelry, gemstones, and ornamental carvings. Due to its extreme toughness, it was historically used for axe heads and weapons.

Geological Facts

Jadeite is one of two minerals recognized as 'Jade' (the other being Nephrite). The most prized variety is 'Imperial Jade,' which is a translucent emerald-green colored by chromium.

Field Identification & Locations

Identify by its high density (heavy for its size), toughness (resistant to fracturing), and granular texture. Found commonly in Myanmar (Burma), Guatemala, and Japan.
