This 14-karat yellow gold curb chain has a diamond-cut finish that accentuates the twist in the links and catches the light, resulting in a subtle glitter ideal for supporting gold and gold-tone pendants and drops. Features a quality tag. A curb chain starts as a cable design, then has its links twisted so they lie flat; the twist gives the links a slightly interlocked look that adds dimension to the chain profile. Diamond-cut versions have facets precision-cut into the links with diamond-tipped tools. The facets are then polished to enhance the light-reflecting properties of the link surfaces.
