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.
