Yi Collection was founded in 2015 by Yi Guo, who spent three years as style editor at Vogue China before launching her own line. Born in Shanghai and trained as a fashion stylist in New York City, she set out to make colorful gemstone jewelry that feels youthful, modern and personal, built on stackable rings and layered necklaces. Every piece is handmade by female artisans in the brand's Bangkok atelier, in 14k or 18k gold or platinum. Each one passes through the hands of six artisans, from the first polish of the rough gemstone to the final setting.
