Costume jewelry pendant necklace in the Art Deco style

This item appears to be a statement pendant necklace featuring a silver-toned metal construction, likely a base metal alloy, paired with a multi-strand twisted rope chain. The pendant itself is designed in a stylized fan or scalloped leaf shape, heavily encrusted with round-cut clear crystals or glass stones of varying sizes. At the center sits a large, oval-faceted clear stone, possibly glass or synthetic spinel, oriented vertically. The metalwork features textured ribbing and milgrain-style detailing that is stylistically consistent with Art Deco or Hollywood Regency jewelry aesthetics, though the construction suggests a more modern mass-produced costume piece. No visible maker's marks, hallmarks, or metal purity stamps are discernible in the image, meaning the identification as costume jewelry is a hypothesis based on surface finish and stone setting styles. The condition appears fair, with some visible darkening or patina in the recessed areas of the metalwork, which could indicate base metal oxidation or intentional antiquing for depth. Without physical inspection, the identity of the stones and the specific manufacturer remain unverified.

Based on my examination of the provided imagery, I have evaluated this pendant necklace as a modern costume jewelry piece executed in the Art Deco style. The construction features a fan-shaped pendant set with what appear to be glass or synthetic crystals in a base metal alloy. From the photo, I can see a multi-strand rope chain and metalwork with a darkened patina; however, I cannot verify the specific metal composition or the chemical nature of the stones without a physical inspection and testing for lead or nickel content. The value is based on the assumption that this is a mass-produced or boutique-level costume piece rather than a designer-signed or precious metal object. The current market for vintage-style statement jewelry remains stable for decorative use, though mass-produced items lack the high-end secondary market demand of signed couture pieces. The estimate provided reflects a piece of this aesthetic quality in fair condition; should the item be identified as a specific high-end designer brand like Trifari or Eisenberg—which cannot be determined from these images as no hallmarks are visible—the value could increase significantly. Conversely, if there is substantial metal fatigue or stone loss not visible in the photograph, the value would decrease toward the lower end of the range. To confirm this hypothetical attribution and value, an in-person examination by a jeweler to check for hidden marks and a professional test of the metal and stone hardness would be required. Documentation of the original purchase or manufacturer would also be necessary to move beyond a style-based appraisal.
