About Us
The National Opal Collection are retail venues with a difference. Located in the CBD areas of Melbourne and Sydney, the showrooms display Australia's most comprehensive range of opals, incorporating a museum where visitors can discover the incredible link between opal and the dinosaurs.
The National Opal Collection has assembled the world’s most important collection of opalized fossils and specimens and displayed them in a unique environment depicting dioramas of pre-historic Australia through to current day opal mining.
The National Opal Collection was formed in 2000, and has its head office located in Melbourne. It is a joint venture between Cody Opal (Australia) Pty Ltd and Gemtec Pty Ltd, who for the past 35 years, have been leading opal exporters, selling opal wholesale to the gem and jewellery trade throughout the world.
Opal is Australia's national gemstone and every sale at the NOC is 100% Australian opal and sourced from the outback fields.
The National Opal Collection is able to provide high quality opal and opal jewellery at very competitive prices. This is due to the company's vertical integration being involved in every step of the process from owning opal mines, cutting and polishing, wholesale/export, design and jewellery manufacturing.
