Australian Boulder Opal Rough

Boulder opal rough is a treasure for opal cutters, lapidaries, and collectors who want to experience the thrill of revealing the colour hidden within the stone. Ethically mined from the opal fields of Queensland, Australia, our rough boulder opal has been naturally formed within ironstone host rock over millions of years.

Each piece has been roughly shaped and is ready to be cut, polished, and transformed into a finished gemstone. Boulder opal is celebrated for its vivid, intense colour play set against a natural ironstone backing — making it one of the most striking and durable of all opal varieties.

From Winton to Quilpie and Yowah, our Queensland rough comes direct from the field at fantastic wholesale prices. If you're looking for a specific size, weight, or colour direction, feel free to get in touch — we have more stock than we've had time to list.
