Jia Jia - JIA JIA's multicoloured Arizona Light necklace is strung from a rainbow-coloured selection of raw faceted sapphires - a stone choice believed to connect with all seven of the chakras - and a drop of pure raw amber for a balanced appreciation of precious stones. Exclusive to MATCHESFASHION, it's handcrafted in the label's New York workshop with a 14kt gold chain and corresponding lobster clasp.
