Playful and vibrant, opals are guaranteed to inject a unique energy into your jewellery layering. SARAH & SEBASTIAN’s latest Aurelia collection is a celebration of natural Australian opals, drawing inspiration from the luminosity of jellyfish drifting through the ocean and sunlight scattering beneath the waves. Crafted in 18-karat yellow gold and white gold, our opal earrings, opal necklaces, opal rings and opal bracelets are all designed in our Sydney studio. Discover the world of opals, and learn more about the unique symbolism and properties of October's beloved birthstone, and uncover the meaning behind each coloured gemstone.
