Jade bangle

Likely nephrite jade (actinolite–tremolite amphibole); possibly jadeite

AI-generated identification · may be incorrect

Hardness about 6–6.5 (nephrite) or 6.5–7 (jadeite); waxy to vitreous luster, translucent green color, and compact fibrous/interlocking crystal structure. The rounded polished form and mottled texture are consistent with jade, though the photograph cannot confirm species.

Physical properties

Formation & geological history

Jade forms through high-pressure, low-temperature metamorphism and metasomatic alteration, commonly in subduction-zone serpentinite mélanges. Important sources include Myanmar, Guatemala, China, New Zealand, Canada, and Russia; ages vary widely by deposit.

Uses & applications

Carved into bangles, ornaments, sculptures, and tools; valued in Chinese and other East Asian cultures for durability and symbolism. Used primarily as a gemstone and decorative material.

Geological facts

Nephrite is an interlocking mass of amphibole fibers, making it exceptionally tough; jadeite is a pyroxene and is generally rarer. Many commercial bangles are treated, dyed, or made from serpentine or other simulants.

Field identification & locations

Check for natural variation, fine fibrous texture, cool feel, and resistance to scratching by steel; reliable identification requires refractive index, specific gravity, spectroscopy, or a gemological laboratory. This appears more like nephrite than vivid jadeite.
