Physical properties
Hardness: 6.0-7.0 (Mohs); Color: Pale yellow to lemon; Luster: Vitreous to greasy; Structure: Interlocking microcrystalline; Cleavage: None/splintery; Specific Gravity: 2.9-3.4
Formation & geological history
Formed in metamorphic environments where calcium-magnesium-rich rocks are subjected to high pressure and heat, or through the infiltration of mineral-rich fluids. Found in river deposits and mountains.
Uses & applications
Used primarily for jewelry (rings, bangles, beads), ornamental carvings, statues, and traditional cultural artifacts, especially in East Asian markets.
Geological facts
Yellow jade is relatively rare compared to green jade; the yellow color is often caused by inclusions of iron ions or impurities within the crystal lattice.
Field identification & locations
Identify by its 'cold' feel to the touch, waxy surface, and lack of visible crystalline grain. Found commonly in Myanmar, China, Russia, and Canada. Collectors look for evenness of color and translucency.
