Omega Collar Necklace 14k Yellow GoldThis 14 karat yellow gold omega necklace measures 17. 25 inches in length and 8 mm in width. The collar style design sits high on the neck, creating a sleek silhouette that works equally well layered with longer chains or worn alone. The omega construction features interlocking metal segments that move fluidly while maintaining structure. The 8 mm width gives the piece presence without feeling heavy, and the secure clasp keeps everything in place
