October Birthstone:


Every birth month is connected to a different gemstone. Those lucky enough to have an October birthday get to enjoy the mesmerizing opal as their birthstone. Opals are known for the range of shimmering colors that dance across their surface and create a striking optical effect. This phenomenon, known as play-of-color, makes every piece of opal gemstone jewelry extraordinary.

A Galaxy in a Stone

Opal was admired by many cultures throughout the ancient world, each giving it a unique meaning. In Arabic lore, opals fell from heaven in the form of lightning, while the Greeks believed they could protect against disease and bestow the gift of prophecy. Opal's shifting rainbow of colors has inspired writers to compare it to volcanos, fireworks, galaxies and more.

Opal's Birthstone History

When people first began wearing the stones connected to their birth months in the 16th century, opal was selected as the original October birthstone. The National Association of Jewelers also chose opal as the modern October birthstone in 1912.

Diversity in Color and Meaning

Each birthstone has its own meaning and symbolism. Opals are associated with love, hope, faith, loyalty, purity and truth. Through its rainbow of colors, this gemstone is thought to reflect the mood of the wearer, to help release inhibitions and to enhance beauty. Some believe that opal symbolizes the virtues of all colored gemstones, making it one of the luckiest gemstones to wear.
