Tiffany & Co. has collaborated with Tmall Super Brand Day to launch the new Tiffany Lock series two-tone gold half-pavé diamond small necklace exclusively online at the Tmall official flagship store for Qixi Festival, known as China's Valentine's Day. Inspired by a gold lock brooch designed by Tiffany in 1883 for a loving couple, the Tiffany Lock series extracts simple and pure lines from ordinary daily objects, conveying the profound meaning of “guarding precious things, nurturing beloved ones.”
