These are extremely rare **vintage cufflinks** from Tiffany & Co., a prestigious American jewelry brand. They are engraved with "TIFF & CO STER 14K" and are a high-end specification, based on **sterling silver** and combined with 14K white gold. This is a discontinued model manufactured around the 1960s-70s, and the design is no longer produced in Tiffany's current line. At the time, Tiffany's produced a small quantity of handcrafted jewelry with more attention to materials and design than they do now, making these rare items that are rarely seen on the market today. --- Features: • Material: Sterling Silver × 14K Gold (with engraving) • Size: Approximately 17mm in diameter • Solid feel and metallic sound • Elegant luster, suitable for both business and formal occasions • Vintage collection, now discontinued and not for sale
