AUSTRALIAN BOULDER OPAL SLABS

Our Queensland boulder opal slabs are mined in Australia and sold direct from the opal fields. Each piece features natural opal colour running through solid ironstone, creating striking patterns and vibrant flashes that can’t be replicated.

These Australian boulder opal slabs are ideal for lapidary artists, opal cutters, jewellery makers, and collectors looking for genuine, untreated opal. Every slab is completely unique and one-of-a-kind, ready for cutting, polishing, carving, or jewellery setting.

Our boulder opal slabs are sourced by the Young Guns, an Australian opal mining crew featured on the Discovery Channel series Outback Opal Hunters.
