Art Deco Style Octagonal Black Enamel Stud Earrings

This pair of vintage-style stud earrings features a geometric octagonal shape influenced by Art Deco design aesthetics. Each earring is constructed with a gold-toned metal frame that encases a smooth, black inlay surface, likely made of enamel or resin to simulate the appearance of onyx. The design is characterized by stepped, concentric borders in gold, which create a structured, architectural silhouette. The pieces measure approximately 15mm to 20mm in width. The earrings utilize a post-and-butterfly clutch closure system, typical of 20th-century costume jewelry. While no visible hallmarks or designer stamps are present in the image, the finish suggests a gold-plated or high-quality gold-tone base metal. The condition appears fair to good; there is visible surface scratching on the black inlay and some dulling of the gold-tone finish on the edges, indicating historical wear. The style is reminiscent of jewelry from the 1980s that revived 1920s Art Deco motifs, often referred to as '80s-does-20s'. The craftsmanship is consistent with mass-produced but stylish boutique accessories of that era, emphasizing bold contrast and symmetry.

I have conducted a visual analysis of these Octagonal Black Enamel Stud Earrings. The pieces exhibit a distinct '80s-does-20s' aesthetic, utilizing geometric symmetry and high-contrast materials characteristic of the Art Deco revival movement of the late 20th century. Based on the visible wear on the stepped gold-tone borders and the lack of hallmarks, I am classifying these as high-quality vintage costume jewelry rather than fine jewelry. The condition is fair; I observed significant surface abrasions on the black resin/enamel inlay and oxidation on the gold plating, which moderately reduces the market value. The market for 1980s boutique jewelry remains stable, particularly for pieces that mimic architectural Art Deco styles. Comparables sold on secondary fashion markets (e.g., Etsy, eBay) typically fall within the $40 to $75 range depending on brand name—such as Monet or Trifari—neither of which is confirmed here. Their lack of designer identification and visible wear suggests they are better suited for a private collection than a high-end auction environment. It is important to note that this appraisal is based strictly on visual inspection of the provided digital imagery. Digital images cannot definitively distinguish between gold plating and solid karat gold, nor can they confirm if the inlay is genuine onyx or synthetic resin. To provide a definitive authentication, a physical examination would be required to perform acid testing for metal purity, microscopic examination of the inlay's grain, and a search for internal makers' marks. Verification of provenance or original packaging would also be necessary to increase the valuation above the current estimate.
