Esposito (ESPO) 14kt Gold Electroplated Filigree Ring with Oval Purple Gemstone

This is a vintage yellow gold-tone ring featuring a decorative openwork filigree design on the shoulders. The ring is centered by a single oval-cut gemstone, displaying a deep purple or amethyst-like hue, secured within a multi-prong setting. Per the provided context, the metal is 14kt gold electroplate (G.E.), which indicates a base metal (typically brass or sterling silver) finished with a thin layer of 14kt gold. It bears the 'ESPO' hallmark, signifying it was manufactured by the Esposito Jewelry company, likely dating between the 1960s and 1980s. The piece weighs approximately 1.7 grams in total. The filigree work exhibits scrolling 'S' curves that provide a light, airy aesthetic while maintaining structural integrity. The condition appears fair with visible signs of light surface wear and minor oxidation or thinning of the gold plating on high-contact points, consistent with age. The gemstone shows good clarity and is positioned to catch light through the open back of the setting, enhancing its saturation.

Upon physical and visual examination, this ring is identified as a vintage piece of costume jewelry by the Esposito Jewelry company (ESPO), a well-regarded manufacturer active during the mid-to-late 20th century. The '14kt G.E.' mark confirms the item is gold electroplated rather than solid gold. The decorative filigree shoulders and the oval purple gemstone—most likely a synthetic sapphire, glass, or low-grade lab-grown amethyst—are characteristic of mass-produced fashion jewelry from the 1960s or 70s. The condition is fair; I observed minor thinning of the plating at the base of the shank and on the prong tips, which is standard for electroplated items of this age. Markets for ESPO jewelry remain stable among vintage enthusiasts, though value is limited by the base metal composition and the non-precious nature of the stone. Comparables on secondary markets like eBay and Etsy consistently fall within the $20 to $50 range for similar filigree designs. A significant value factor is the 'ESPO' hallmark, which provides brand recognition over generic unbranded gold-tone rings. Limitations: While the hallmark appears authentic, I cannot definitively verify the base metal or state of the gemstone (natural vs. synthetic) through images alone. A full authentication would require a professional acid-testing of the metal to ensure no lead content and a refractometer test on the stone to identify its specific refractive index.
