The Fascinating History of Opals

Opals have captivated people for thousands of years with their remarkable flashes of colour. Unlike any other gemstone, each opal is completely unique, displaying an ever-changing play of colour that has fascinated civilisations throughout history. Today, Australia is synonymous with precious opals, but the story of these extraordinary gemstones stretches far beyond its famous outback mines.

If you're interested in purchasing an opal, our guide to Australian vs Ethiopian opals for UK buyers explains the key differences between these two popular varieties.

The Earliest Known Opals

The first known opals were discovered in what is now Slovakia over 2,000 years ago. These deposits supplied the Roman Empire, where opals became one of the most treasured gemstones of the ancient world.

The Romans admired opals because they appeared to contain the colours of every other precious stone. They believed opals symbolised hope, purity and good fortune, making them highly sought-after among wealthy families and nobility.

For centuries, these European deposits remained the world's primary source of precious opals.

Australia Changes Everything

The global opal industry changed forever during the late nineteenth century when large deposits were discovered in Australia.

In 1889, significant opal fields were uncovered at White Cliffs in New South Wales. This was followed by discoveries at Lightning Ridge, Coober Pedy, Andamooka and later Mintabie.

These discoveries transformed Australia into the world's leading producer of precious opals, a position it held for well over a century.
