How Much is an Australian Opal?
- What is an Australian opal?1 Answer1stDibs ExpertNovember 2, 2021Today, Australia and Ethiopia are the two largest producers of opals. Historically, most of the world’s opals were mined in South Australia. The stone is so closely associated with Australia that in 1993 it became the national gemstone. There are five types of precious opals: boulder opal, fire opal, crystal/water opal, black opal, and white/light opal. Each variety is distinguished by its color. Shop a collection of vintage and modern Australian opal jewelry from some of the world’s top jewelers on 1stDibs.
