Discover Australian Opals

Australian Opals are naturally formed gemstones mined in outback Australia. They were formed by hydrated silica (sand) and water from the Great Artesian Basin; a sea that once covered inland Australia. All Australian Opals are unique, one and only, and are prized as one of the most valuable and demanded gemstones in the jewelry and collectors market today.

Authentic Opals, Guaranteed!

All of our opals are either mined by our team or miners that we know and trust. We guarantee that all of our opals are authentic, natural and ethically sourced. Australian Opals are governed by strict sustainability laws. We also promise that our opals are not treated. We do not sell opal doublets or opal triplets; they are all full, solid opals from Australia. We also offer a lifetime guarantee for natural cracks that may form in our opals.

Secure Shipping

All purchases over $200 on our website come with complimentary shipping and insurance. We ensure all opals are sent in secure, well packed parcels with low declared values. Upgrades on shipping are available to both EMS and Fedex, and can be offered as complimentary with higher value purchases.
