perfect jewellery gifts designed and made in Wales

Wales is a country with a deeply rich culture built on a foundation of poetry, profound words, music, stunning landscapes and a complex history.
Mari, being very proud of her Welsh origins, wants to express that within and through her work. She has found a myriad ways in which to represent and preserve Wales in everything she creates, and it is for all to see in her Gallery in Llandeilo, set in a stunning part of our beautiful country.
