Huge opal sells for nearly $144,000 at Alaska auction

JUNEAU, Alaska (AP) — A gemstone, billed as one of the largest gem-quality opals in existence, has been sold for nearly $144,000 at auction in Alaska on Sunday (Feb. 20, 2022). The auction house, Alaska Premier Auctions & Appraisals, said the opal, dubbed the “Americus Australis,” weighs more than 11,800 carats. It also has a long history. Most recently, it was kept in a linen closet in a home in Big Lake, north of Anchorage, by Fred von Brandt, who mines for gold in Alaska and whose family has deep roots in the gem and rock business. The opal is larger than a brick. Von Brandt said the stone has been in his family since the late 1950s, when his grandfather bought it from an Australian opal dealer.
