Established in 1998, Mari Thomas Jewellery is one of Wales’ leading artists and contemporary jewellers. Designer-founder Mari’s passion for designing and creating shines through in her several distinct collections, one-off pieces and commissioned works.

Available online and through her own gallery in Llandeilo, South Wales, Mari’s pieces are highly sought after and collectible. Her collections draw heavily on her Welsh heritage, landscapes, culture, the Welsh language and the process of thoughts and designing itself. At the core of all of her work, Mari Thomas is a designer. Using jewellery as an expression, Mari creates wearable art that tells a story.

She frequently works with both private and corporate clients to design and create bespoke commissions, ranging from platinum and diamond engagement rings to National Eisteddfod crowns.
