Located some 1000km NW of Brisbane, the Opalville mine, Lease No. 135 is famous for the spectacular Galaxy opal, an estimated 550 carat specimen (on a matrix 9.7x8.1x5.7cm) found in October 1989. The finder was opal miner Josip Grguranic, and the stone was initially exported to Europe as gem rough, where a Swiss goldsmith made an Australian collector aware of its existence. A syndicate of Swiss and Australians was formed to purchase the stone and it was sent back to Australia to be polished by Michael Walsh of Oplex Natural Gems, Melbourne.
