Opals are commonly thought to be found mainly in Australia, and 85% of them are, but there are many other areas of the world where they are mined as well - The US, Ethiopia, Honduras and Brazil.
On February 26, the American Museum of Natural History will host an exhibition of 25 beautiful iridescent opals for public view, in the Museum’s Harry Frank Guggenheim Hall of Minerals. The featured opals will be from all the mining locations mentioned and will illustrate the diversity of the gems.
Opals are renowned for their colorful iridescence and they scatter light beautifully. You can read more about the display and view some of the exhibits on the Natural History Museum's website.
