AI Appraisal Estimate

This antique jewelry set consists of a stick pin and a pendant necklace, likely dating from the early 20th century (Edwardian era, circa 1900-1915). The items are presented in an original velvet-lined, silk-interior presentation box which shows significant age-related wear, including fraying at the hinges and discoloration. The stick pin features a yellow gold-toned metal shaft terminating in an open-work scroll head set with a vibrant deep green center stone, possibly a synthetic spinel or glass common to this period. Adjacent to it is a lavallier or bar-style pendant on a fine cable chain. The pendant features a geometric circular drop with concentric wirework and a tiny accent stone, likely a seed pearl or small diamond chip, at the center. The craftsmanship is characteristic of the transitional period between late Victorian and Art Deco, utilizing lightweight wire designs and delicate filigree-like patterns. While no hallmarks are visible in the photograph, the style and context of a grandmother's heirloom suggest they could be 10k or 14k gold, or high-quality gold fill. Condition-wise, the pieces appear intact, though the metal shows a darkened patina and the velvet casing shows signs of heavy conservation needs.

I have conducted a visual examination of the Edwardian-era stick pin and lavallier pendant set. Based on the open-work scroll head and geometric circular drop, these pieces reflect the delicate aesthetics typical of the 1900-1915 period. The dark patina suggests either gold-fill with wear or high-karat gold with oxidation. The presence of the original, albeit aged, presentation case adds significant provenance value, as complete sets from this era are increasingly rare. While the stones—likely synthetic spinel and seed pearls—were common for the time, they remain in good condition despite the box's deterioration. The current market for Edwardian jewelry remains stable, with collectors favoring 'feminine' wirework and 'Lavallier' styles. The $350-$600 range reflects the transition from gold-filled to 10k/14k gold assumptions. This appraisal is limited by the inability to perform physical testing. A definitive valuation requires in-person metal acid testing or XRF analysis to confirm gold karatage and a gemological examination (refractive index/magnification) to distinguish between glass, synthetic, and natural gemstones. Provenance documentation, such as family receipts, would further bolster the authenticity of its Edwardian origin.
