The Raw Emerald Earrings Nudo feature the same raw Colombian emerald that defines the collection, set into a copper knot-shaped structure. The stone is not cut or polished — its rough texture, edges and deep green are exactly what we seek. Colombia produces over 70% of the world’s emeralds. Those in this collection are ethically sourced and worked by artisans using traditional filigree techniques from Mompox. Each pair is unique: the emerald’s size, tone and shape vary from piece to piece.
