Physical properties
Hardness: 6.5-7 Mohs; Color: Pale yellow to deep golden amber with translucent core; Luster: Vitreous to greasy; Crystal structure: Monoclinic; Cleavage: Good in two directions (rarely seen in massive form); Specific Gravity: 3.25-3.35
Formation & geological history
Formed deep within the Earth's crust under high pressure and relatively low temperature conditions. The yellow coloration is often due to iron inclusions or staining within the crystal lattice, typically associated with secondary weathering or oxidation processes.
Uses & applications
Predominantly used for high-end jewelry, ornamental carvings, and talismans. Highly valued in Asian cultures as a symbol of wealth and prosperity.
Geological facts
Jadeite is the rarer and harder of the two minerals known as 'Jade'. The yellow variety is less common than green and is highly sought after by collectors for its warm, sun-like glow and symbolic connection to the 'Gold' element.
Field identification & locations
Identify by its exceptional toughness (resistance to chipping), cool touch, and dense weight. In the field, look for a smooth, waxy 'rind' or skin on river-worn cobbles. Found mostly in Myanmar, Guatemala, and Russia.
