中英對照讀新聞》Huge opal sells for nearly $144,000 at Alaska auction 阿拉斯加拍賣會上 巨大蛋白石以近14萬4000美元售出
A gemstone, billed as one of the largest gem-quality opals in existence, was sold for $143,750 at auction in Alaska.
The opal, dubbed the "Americus Australis," weighs more than 11,800 carats.
Most recently, it was kept 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 and is broken into two pieces, which von Brandt said was a practice used decades ago to prove gem quality.
Von Brandt said the stone has been in his family since the late 1950s, when his grandfather bought it from an Australian opal dealer named John Altmann.（AP）
