We also offer affordable composite opal stone jewellery, such as doublets and triplets. Each opal is hand-selected for its quality, brilliance and natural beauty, and we do not use synthetic or lab-created opals.
Yes, all our opal jewellery contains ethically sourced stones from Australia and we work with Australian jewellers and suppliers. Opal from Australia is the benchmark for quality, durability and rarity, with over 90% of the world's gem opal supply coming from Down Under. We do not sell jewellery with non-Australian opal gemstones.
Most gold opal and diamond jewellery and opal gemstone purchases come with a digital Certificate of Authenticity, detailing the type, origin and characteristics of the piece. We can also provide certification for any other opal jewellery upon request.
