Made to Hold a Memory
Oyster Theory was born in Adelaide during a deeply personal chapter of my life, inspired by creativity, coastal beauty and the importance of treasuring each special moment. Created in loving memory of my husband, Ian, every piece is made to tell a story and keep a meaningful memory close.
From oyster and scallop shell keepsakes to trinket dishes, wedding gifts and memorial pieces, each creation is individually decorated with beautiful artwork, florals, gold leaf and glossy finishes. Thoughtful design, quality materials and careful craftsmanship ensure every piece feels as unique as the person and occasion it celebrates.
