October Birthstones: All About Opal & Tourmaline

In terms of birthstones, those born in October are among the luckiest. The October birthstone consists of two amazing gems, tourmaline and opal, rather than just one. Both are renowned for their rainbow of hues, which provide countless opportunities for beauty and individual expression (1). They perfectly capture the vibrant, dynamic, and ever-changing essence of autumn with their distinctive play of light and breathtaking hues.

History of October Birthstones

In ancient Rome, opals were highly prized because they were believed to bring good fortune and even invisibility to those who carried them. They were thought to improve vision and intuition during the Middle Ages. Due to its pyroelectric qualities, which captivated early gem traders, tourmaline was prized for its capacity to both attract and repel (3). These myths demonstrate how enchanted the birthstone of October has always appeared, inspiring wonder and awe in people from all walks of life.

History of Tourmaline

Like the gem itself, tourmaline has a colorful past. Green tourmaline was frequently mistaken for emerald and red for ruby by ancient traders.

While Chinese Empress Dowager Cixi loved pink tourmaline, making it a favorite in Asia, Maine tourmaline rose to great value in the United States in the 1800s. Its international journey brings to light a gemstone whose beauty and mystique have always won people over.

For thousands of years, people have valued opals. Opals were regarded as the most valuable gemstones by the ancient Romans, who valued them as representations of purity and hope. Opals were considered lucky stones in the Middle Ages because of their color play, which was thought to embody the qualities of all gems. Because of its brilliant rainbow flashes, traders used to refer to opal as the "queen of gems." Folklore was also captivated by opal; some cultures thought the stone could make one invisible, while others saw it as a protection and truth talisman.
