How much is the Aurora Australis opal worth?
1 Answer
No one can say for certain how much the Aurora Australis opal is worth today. In 2023, one expert estimated it was likely worth $1.9 million. However, it is difficult to know how much it might actually sell for. The Aurora Australis opal has a carat weight of over 17,000 and weighs around 7.5 pounds. Today, more than 35 years after its discovery, the opal is on display at the Altmann + Cherny showroom in Sydney, Australia, where it is likely to remain. Find a variety of opal jewelry on 1stDibs.
