The Top Ten: Royal Opals

FREDRIK VON ERICHSEN/AFP/Getty Images

October babies, let's face it: you've got a pretty cool birthstone. Opals come in a variety of colors, and often they look like they're literally glowing from within. Most of the world's opals are mined in Australia, so it's no surprise that it's also the country's national gemstone. Royals have been attracted to opals for centuries, from the "Burning of Troy" opal given by Napoleon to Josephine all the way to the Duchess of Sussex's engagement earrings, though many royal collections lack major opal pieces. Today, we're running down ten of the most intriguing opals in royal collections past and present.
