The oval, cut and polished stone has a harlequin pattern with dominant red, green and blue colors against a black background.
It weighs 180 carats and it measures 3 inches by 1.8 inches. The rarity of the opal comes from its size and strong, vibrant colour play.
Dug from an old sea-bed it has the distinctive impression of a star fish on its back. It was valued at AUD$1,000,000 in 2005.
The Aurora Australis is the first large, fine Australian opal mentioned in literature. Charlie Dunstan had found another large opal previously, but its blue-green colour play was not considered valuable at the time although the stone weighed about 12 ounces (close to 1860 carats).
At a depth of approximately six metres, Charlie Dunstan found the brilliant gem. This treasure was rumored to have brought Dunstan 100 pounds.
Altmann & Cherny purchased the opal in a semi-rough state (a rub). They cut and polished the opal into its oval shape. Realising what a true gem they had, they named it “the Aurora Australis “ after the bright southern lights in the night sky.
