Jia Jia - The rainbow spectrum of fancy sapphires that make up JIA JIA's 14kt gold Arizona Rainbow necklace connect to all seven chakras of the mind and body, reflective of founder Jia-Jia Zhu's celebration of the natural world. It's crafted by hand in the label's New York workshop using stones that have been cleansed of previous energies, then fitted with a lobster clasp.
