The omega chain - a smooth, ribbon-like chain with a distinctive flat surface that lies completely flush against the skin - has a luxurious drape quality that other chain constructions cannot match. The diamond-cut finish on this 2mm 18K yellow gold over sterling silver version adds faceted light catch to the smooth omega surface, creating a chain that shimmers in the warm gold tone as it moves. The 3-inch adjuster allows versatile length positioning between two preferred collarbone positions. A chain that wears as a polished everyday foundation piece or layers as the warm gold element in a mixed-metal neck stack.
