An 18K yellow gold over sterling silver curb chain necklace with a two-tone finish at 18.5 inches - the layering chain that works as the warm-metal component in a mixed-metal arrangement or as a statement on its own. At 7/16 inch wide, the curb links have genuine visual weight that reads clearly at the collarbone without requiring pendants to justify the piece. The two-tone construction creates a subtle play of color as the chain moves - warm gold faces catching light differently from the silver-toned elements. A push button closure at the plating section adds a distinctive, considered design touch. The chain that bridges yellow gold and sterling silver jewelry without requiring a commitment to either.
