Jadeite bi pendant necklace (unauthenticated)

This piece features a pale, translucent white to light greenish stone carved into the traditional circular form of a Chinese bi disc with a central circular aperture. The pendant is suspended from a metal chain, which appears to be constructed of interconnected bar and link components in a silver-tone metal that may be white gold, platinum, or silver, though no metal purity marks are legible from the photograph. The stone exhibits a smooth, polished surface with subtle natural internal mottling and cloudiness, characteristics visually consistent with jadeite or nephrite jade, although gemstone testing is required to verify the exact mineral composition. The setting includes a bail that grips the outer rim of the disc and connects to the articulated chain. There are no clearly visible maker's marks, hallmarks, or signatures apparent in the image. The item is resting inside a pink, heart-shaped plastic container. The overall appearance is consistent with modern or vintage East Asian-inspired jewelry design, but the exact age, origin, and material authenticity remain unverified without physical and gemological inspection.

Based on what I can see in the photograph, this necklace features a pale, translucent to light greenish carved stone disc resembling a traditional Chinese bi pendant, suspended from a silver-tone metal chain. I can't verify from a photo whether the stone is true jadeite, nephrite, or a lesser green-tinted simulant, nor can I determine the metal purity of the chain or setting without physical inspection. There are no clearly visible maker's marks or hallmarks apparent in the image. My value estimate of $150 to $350 assumes that the piece is composed of genuine jadeite and precious metal. General market demand for East Asian-inspired jade jewelry remains steady, particularly for traditional bi pendant designs. However, if physical testing reveals that the stone is a treated polymer-impregnated jadeite, a lower-value green simulant, or glass, and the metal is base metal rather than precious metal, the market value would drop significantly to a range of $25 to $75. What would be needed to confirm authenticity and material composition includes in-person gemological examination, scientific testing such as FTIR or specific gravity tests, and hallmark verification by a qualified specialist.
