I had been looking for real Australian Opals for a long time. Online shops are aplenty but authenticity is the real issue until I found Flashopal - an Australian store that specializes in real Australian opal stones, handmined and handpicked in and around Queensland itself. Pricing is not something Opals can handle. They are precious and the sticker price does prick a bit but with this quality and assurance of knowing that you are getting the real stuff makes it worth the price.
Was looking for an opal seller, there is hardly anyone in the trade these times. Had no issues with them. 100% recommend!
