ABOUT CASSANDRA
Cassandra Mamone is widely regarded as one of the best jewellery designers in Adelaide and a leading name in Australian fine jewellery. With a career spanning over two decades, Cassandra has earned her reputation through refined craftsmanship, emotional storytelling, and a signature style that blends modern luxury with timeless elegance.

Known for her perfectionism and commitment to meaningful design, Cassandra meticulously selects only the finest materials—from pure white natural diamonds to striking precious gemstones. Pieces are handmade, with intentional detail and symbolic touches, such as her signature ruby (her birthstone) set on the inside of select engagement rings.
As one of Australia’s top bespoke jewellers, Cassandra’s work has become synonymous with heirloom quality and emotional value. Her clients seek her out not just for beautiful pieces—but for jewellery that holds memory, legacy, and depth.
An alumna of the Gemological Institute of America (GIA), Cassandra specialises in engagement rings, bespoke fine jewellery, and jewellery remodelling that breathes new life into treasured heirlooms.
