Collection: Ostreidea

Welcome to the Ostreidae collection, proudly stocked at Betty & the Brands. Ostreidae is an independent, female-founded jewelry studio that hand-assembles sculptural marine objects right on the Brighton seafront by the marina. We believe in accessible, contemporary luxury that is designed to be lived in—not left tucked away in a velvet drawer. Our collection embraces the organic, tactile beauty of the coast, offering highly durable, water-safe pearl jewelry that effortlessly transitions from a morning sea swim to an evening out. Whether you are layering delicate floating pearls or styling a bold, asymmetrical statement chain, every piece merges modern architectural design with the raw, luminescent elements of the ocean.
