The majority of the world’s precious opal comes from Australia, where unique geological conditions allowed the formation of this rare gemstone. Most light opal is found in South Australia, black opal in New South Wales – especially Lightning Ridge – and boulder opal in Queensland.
Opal is Unique
You may well see all the colours of the rainbow in a single precious opal. As early as the 1st century A.D., the Roman philosopher Pliny wrote:
"For in them you shall see the living fire of ruby, the glorious purple of the amethyst, the sea-green of the emerald, all glittering together in an incredible mixture of light."
No other gemstone can display all the colours of the spectrum in such an infinite variety of shades, patterns and brilliance. No two are identical; for this reason the proud owner can delight in the fact that their gem is unique.
