The Lentsius jewellery line is the creation of designer Kairi Lentsius and her craftsman father, Mart. Kairi earned her bachelor's from Pallas University of Applied Sciences and her master's from the Swedish School of Textiles. Post-graduation, she showcased her collections at both London and Stockholm Fashion Weeks. Her accolades include a second-place finish in the Estonian Designers Union's "Men's Thing" competition in 2013, a nomination for the Young Designer Award SÄSI in 2016, and an honourable mention for her Telk collection at the 2022 BRUNO Estonian Product Design Awards. Beyond running Lentsius, Kairi also serves as a fashion design lecturer at Pallas University of Applied Sciences. The brand is committed to sustainability, upcycling waste from the metal and wood industries to create new pieces. With timeless, seasonless designs as their aesthetic cornerstone, nearly all Lentsius jewellery is crafted from a single material to minimize waste and streamline production. All items are handmade in Tartu, Estonia.
