An 18K yellow gold over sterling silver 3mm rope chain necklace measuring approximately 22 inches long by 0.78 inches wide with hinged closure - the Turkish-crafted rope chain in a length that sits at the collarbone-to-chest transition, making it the chain that works with pendants at a deeper drop than standard 18-inch chains allow. The rope construction creates interlocking diagonal links that produce the characteristic twisted visual pattern. At 3mm, the rope has genuine visual weight. Hinged closure. Turkish artisan craft in a foundational fine chain format.
