All our opals are direct from Australia, from our mines and cut and polished from all opal fields throughout Australia. None of our opals have been treated or enhanced in any way (unless specified). Photographs have been enlarged to benefit the buyer. Do yourself and us opal miners a favor and only buy NATURAL OPALS. We have been Mining, Exporting and Cutting beautiful Australian Opals for well over 12 years. LOVE OPALS, LOVE LIFE.
