Top best answers to the question «What's the most expensive opal ever found»

The largest and most valuable single piece of rough gem opal is the Olympic Australis, a 3.45-kilogram, 17,000-carat stone estimated to be worth about $1.9 million.

The Virgin Rainbow

This $1 million opal is the world's most expensive. It was discovered in 2003 by John Dunstan (who has been featured in the Outback Opal Hunters TV show) in the same opal fields as the Fire of Australia. Another interesting fact is it formed and was found within an ancient cuttlefish skeleton.

In terms of polished stone, the Virgin Rainbow, a rare crystal opal that's also owned by the South Australian Museum, is the world's most expensive opal on a per gram basis, valued at $750,000.
