Costume jewelry statement necklace

This is a statement necklace featuring a bold, geometric design composed of three interconnected diamond-shaped metal sections embellished with black enamel or resin cabochons and clear paste rhinestones. The metal setting appears to be a silvery tone base metal, possibly rhodium-plated or polished alloy. The central pendant drops feature a layered structural design with smaller rectangular black accents and pavé-set clear rhinestones bordering the central square cabochons. The necklace suspends from a textured chain link with a clasp and extender chain visible at the top. There are no visible maker's marks or signatures apparent in the provided photograph, so the identification relies entirely on visual characteristics such as the Art Deco revival geometric styling and materials typical of mid-to-late 20th-century costume jewelry. The overall condition appears generally clean with intact stones, though minor wear to the metal finish cannot be ruled out without physical inspection. The item is unauthenticated and unverified.

Based on what I can see in the photograph, this statement necklace exhibits striking Art Deco revival geometric styling featuring interconnected diamond-shaped metal sections, black enamel or resin cabochons, and clear paste rhinestones. However, I cannot verify the exact metal composition, stone quality, or presence of maker's marks from a photo alone, and I would need physical inspection to confirm these details. The item is unauthenticated and unverified, and there are no visible signatures to suggest attribution to a specific maker. My valuation of $75 to $150 reflects typical market behavior for mid-to-late 20th-century costume jewelry of this aesthetic and quality level. Demand for vintage statement necklaces is driven largely by decorative appeal and wearability rather than precious material value. If the piece were to undergo in-person examination, hallmark verification, or expert appraisal, and turned out to be an unmarked piece by a notable high-end costume jewelry house, the value could potentially shift upward. Conversely, if it is determined to be a later reproduction or a mass-market piece 'in the style of' vintage costume jewelry, the value would likely decrease to the lower end of the spectrum, around $25 to $50. Physical inspection and potential provenance documentation would be required to fully confirm its manufacturing period and construction quality.
