Modernist-style sterling silver and faceted blue gemstone pendant

This item appears to be a modernist pendant featuring a large, round faceted gemstone, stylistically consistent with aquamarine, blue topaz, or blue zircon, though the exact mineral cannot be established from the photograph alone. The stone is secured in a bezel setting at the base of a sculptural, curvilinear sterling silver frame. The frame consists of two elongated, graceful silver wires that converge at a tapered, integral bail. The metal exhibits a bright luster consistent with sterling silver, and a partial mark is visible on the bail which may be a fineness stamp, though it is not fully legible in the image. The pendant is suspended from a thin box-link chain. The overall craftsmanship appears to be of high quality, featuring smooth solder points and a polished finish. There is minor surface wear and light tarnishing visible in the recessed areas, consistent with age and use. The aesthetic is characteristic of mid-to-late 20th-century contemporary jewelry design. This identification is based on visual stylistic features as no definitive maker's name is clearly legible.

Based on my visual analysis of the provided image, this pendant exhibits the aesthetic hallmarks of mid-to-late 20th-century Modernist jewelry. I can observe a large, round faceted blue gemstone set in what appears to be a sterling silver curvilinear frame. While the stone's color suggests aquamarine or blue topaz, I cannot verify the exact mineral species or whether it is natural or synthetic from a photograph; scientific testing like refractive index measurement would be required. The silver shows a bright luster and possible fineness marks, though I cannot definitively read a maker’s hallmark or confirm metal purity without an in-person acid or XRF test. My value estimate of $150–$350 assumes the piece is sterling silver and features a high-quality semi-precious gemstone. This range reflects the general market demand for contemporary, artist-designed jewelry of this style, where value is driven by craftsmanship and aesthetic appeal. I must emphasize that this attribution remains a hypothesis; if the piece were found to be a base metal reproduction or featured a glass stimulant rather than a gemstone, the value would likely fall below $50. Conversely, if the mark were identified as belonging to a highly collectible studio jeweler, the value could exceed this range. To confirm authenticity and secure a more precise valuation, a physical examination of the hallmarks and gemstone under magnification, along with any available provenance documentation, is necessary. The current estimate is based on the item as it appears, accounting for minor surface wear and light tarnishing consistent with a vintage piece.
