Green jade bead necklace

Most likely nephrite jade (a tough, interlocking amphibole aggregate; commonly tremolite–actinolite), though jadeite jade or dyed serpentine is possible from the image alone.

AI-generated identification · may be incorrect

Dark green, polished, waxy-to-vitreous luster with mottled translucency; nephrite hardness about 6–6.5 Mohs, jadeite about 6.5–7. Both are cryptocrystalline and typically lack visible cleavage; density is roughly 2.9–3.3.

Physical properties

Formation & geological history

Nephrite forms through metamorphism and metasomatic alteration of ultramafic or carbonate rocks, commonly in mountain belts; jadeite forms in high-pressure subduction zones. Geological ages vary widely by deposit.

Uses & applications

Used for beads, carvings, jewelry, tools, and ornamental objects; jadeite of vivid, translucent “imperial” green can be extremely valuable.

Geological facts

Jade is defined commercially as either nephrite or jadeite, not by color alone. The small contrasting beads may be metal, glass, or another stone.

Field identification & locations

Look for natural color variation, fibrous texture, exceptional toughness, and cool density; scratches, dye concentration in cracks, or uniform color can indicate imitation or treatment. Major sources include Myanmar, Guatemala, China, Canada, New Zealand, and Russia.
