Gold filigree and pink coral earring

This single earring features a delicate, handcrafted filigree design in yellow metal, likely gold or gold-filled, surrounding a central oval-cut pink coral cabochon. The overall piece measures a modest size, typical of a daily-wear dangling or drop stud earring, complete with a straight post soldered to the upper suspension loop. The central coral stone exhibits a soft, pale pink to peach coloration with natural subtle variations in tone and a smooth, polished domed surface. The surrounding wirework creates an open, floral-like or scalloped openwork metal frame featuring interconnected loops and curls characteristic of traditional filigree craftsmanship. There is no visible maker's mark, hallmark, or stamp clearly identifiable from the provided image. The piece displays minor signs of gentle surface wear and a light patina consistent with vintage or antique costume and fine jewelry, but remains structurally intact with no glaring damage or missing wire components. The stylistic elements are consistent with mid-20th-century or earlier Mediterranean artisanal jewelry traditions, though the exact metal purity and stone origin remain unverified without physical testing.

Based on what I can see in the photograph, this single earring features a handcrafted filigree design in a yellow metal housing an oval-cut pink coral cabochon. I can observe delicate wirework and a smooth, polished domed coral surface with a soft pink-to-peach tone, showing a vintage patina consistent with mid-20th-century artisanal jewelry traditions. However, I cannot verify the exact metal purity, such as whether it is karat gold or gold-filled, nor can I definitively test the natural origin of the coral without physical inspection. There is no clearly identifiable maker's mark or hallmark visible in the image. My valuation estimate of $150 to $250 assumes the piece is crafted from solid gold and genuine Mediterranean coral, reflecting typical market behavior for vintage filigree costume and fine jewelry items of this style and period. If physical testing reveals the metal is merely gold-plated base metal or the coral is dyed or synthetic, the value would likely decrease to the $50 to $100 range. To confirm authenticity, metal purity, and stone origin, an in-person examination, hallmark verification, and gemological testing would be necessary.
