The Olympic Australis Opal is believed to be the largest gem opal ever found. Found in 1956 at the "Eight Mile" opal field in Coober Pedy, South Australia, it was found at a depth of 30 feet and so named because the Olympic Games were being held in Melbourne at the time. The Olympic Australis consists of 99% gem opal, with the remainder of 1% being the soil still attached to the stone. It weighs 17,000 carats (3450 grams) and is 280 mm long (11 inches) by 120 mm, by 115 mm. It was valued at AUD$2,500,000 in 2005.
