Mass Lee Jewellery.

Located on the antique-centric Kloosterstraat, Mass Lee is the collaborative atelier of designers Josefine Mass and Dabin Lee. The duo merges Finnish minimalism with the intricate technicality of Korean craftsmanship to create sculptural "art jewelry" that feels both avant-garde and wearable. Each piece is handcrafted in-house, often using recycled metals sourced from a local refinery and stones from the nearby diamond district. The aesthetic is defined by a playful, organic sense of form—think molten textures, irregular pearls, and fluid silver shapes that look like miniature gallery sculptures. Beyond their rotating seasonal collections, the shop functions as an open studio where visitors can see the process firsthand or commission bespoke engagement and wedding pieces. It is a standout for those seeking jewelry that prioritizes narrative and hand-wrought character over mass-market polish.
