11 of the Most Mesmerizing Opal Jewels and Watches

Artful creations by Dior, Cartier, and Harry Winston that feature October’s alluring birthstone

There is perhaps no gem quite as magical as the opal, the fiery birthstone for those born in October. As far back as 75 AD, the Roman scholar Pliny observed, “Some opali carry such a play within them that they equal the deepest and richest colors of painters. Others simulate the flaming fire of burning sulphur and even the bright blaze of burning oil.” He marveled at how the mesmerizing gem encompasses the red of ruby, the green of emerald, the yellow of topaz, the blue of sapphire, and the purple of amethyst.

Indeed, opals have long been shrouded in mystery and folklore, and they have been thought to have supernatural origins and powers in many cultures. Arab tradition says that opals were created by a lightning strike and the flashes of color within are trapped lightning. In ancient Greece, they protected the wearer from disease and illness. And in the Middle Ages, it was dubbed the “magician’s stone”.

Today, a myth pervades that opals bring bad luck if worn outside the month of October, a superstition that is thought to have begun with Sir Walter Scott’s 1829 gothic novel Lady of the Mist. In the story, the character Lady Hermione wears an opal clasp in her hair that changes color based on her emotions. When holy water is eventually flung at the jewels to extinguish their frightening powers, the heroine is reduced to a heap of ashes that evening. (She in fact died by poison, but since the novel was released in chapters, the rumor had already spread.) The extraordinary beauty of opals, however, far outweigh any of these unfounded negative associations. 

Below, the most beautiful opal creations to be worn in October—or, if you dare, any time of the year.
