Collection: Australian Boulder Opal

Australian boulder opal is one of nature's most extraordinary gemstones - formed within the cracks and cavities of ironstone host rock deep in the Queensland outback. The ironstone matrix is left as a natural backing, giving boulder opal its characteristic depth, durability, and the dark background that makes its play-of-colour so vivid and intense.

Every piece in this collection has been ethically sourced directly from a family-run mining operation in Queensland Australia, ensuring full provenance, transparency, and responsible practices. From rings and pendants to earrings and loose polished stones, each boulder opal is a one-of-a-kind piece shaped by millions of years of geological activity - no two are ever alike.

Whether you're drawn to electric blues, rolling greens, reds or deep amber flashes, browse the collection and find the boulder opal that speaks to you.
