MoMA Exclusive: Designer Morgan Thomas—founder of the Black-owned, women-operated brand Yam—is dedicated to creating new-yet-nostalgic jewelry with upcycled materials, vintage silhouettes and cheeky nature motifs in mind. This special-edition Maddy Necklace is crafted in New York with a colorful handmade millefiori (wildflower) charm sourced from a small studio in Murano, Italy. Each bead is one-of-a-kind and the deadstock cotton cord can be styled in varying lengths, long or double-wrapped to create a choker. The Yam Maddy Necklace charm measures 0.67" with a cord length of 48”.
