October boasts the unique distinction of having two recognized birthstones: the iridescent opal and the vibrant tourmaline. Both gemstones offer a dazzling array of colors and possess fascinating histories, making them cherished adornments for those born in the tenth month. While opal holds the position as the traditional October birthstone, pink tourmaline was added as a modern alternative in 1912, offering a wider range of options for celebrating October birthdays.
History and Lore
Opal’s history is rich with folklore and symbolism, stretching back to ancient times. Originating from the Sanskrit word “upala,” meaning “precious stone,” the name evolved into “opalus” in Latin. Ancient civilizations attributed magical properties to opal, with some believing it contained lightning or offered prophetic powers and protection from disease. Europeans considered opal a symbol of purity, hope, and truth, and for centuries, it was believed to embody the virtues of all colored stones. In contrast, pink tourmaline gained prominence later in history, particularly captivating the Chinese Empress Dowager Tzu-Hsi in the late 1800s. She amassed a significant collection, even being buried with pink tourmaline, demonstrating the gem’s esteemed status.
Geological Formation and Sources
Opals are formed from silica spheres arranged in a regular pattern, with water interspersed between them. This unique structure causes the “play-of-color,” the iridescent effect that makes opals so captivating. The size of these spheres dictates the range of colors displayed. Historically, opals have been mined in diverse locations, including Ethiopia and Australia, each contributing to the gem’s distinctive character. The sources for tourmaline are less detailed in the provided materials, but it is noted that significant quantities were once sourced from California, specifically to satisfy the demands of Empress Tzu-Hsi.
Gemological Properties
Opal is valued for its shifting colors, a phenomenon known as “play-of-color.” Precious opals, constituting only 5% of all opals, exhibit this iridescence, reflecting tiny points of sparkling jewel colors. Opals come in various colors, including black (the rarest and most valuable), gray, green, and white, and can even be colorless. The composition of opal consists of small spheres of silica.
Pink tourmaline, the modern October birthstone, occurs naturally and displays a striking pink hue with variations throughout the color spectrum. It forms in distinctive prism-like crystals with long hexagonal structures. Tourmaline, in general, is known for its occurrence in many different colors, with some crystals even exhibiting multiple colors, known as watermelon tourmaline. The provided sources do not detail the chemical composition or hardness of either gemstone.
Symbolism and Metaphysical Beliefs
Throughout history, both opal and tourmaline have been imbued with symbolic meaning. Opal has been associated with luck, hope, and purity. Bedouins believed opal held lightning, while ancient Greeks thought it bestowed the gift of prophecy and protection. Pink tourmaline, on the other hand, is linked to friendship, compassion, and balance. The Egyptians believed tourmaline’s many colors originated from traveling down a rainbow from the sun to earth. Rose quartz, sometimes considered an alternative October birthstone, is associated with love and self-forgiveness.

Pink Tourmaline: A Closer Look
Pink tourmaline emerged as the modern October birthstone in 1912, offering an alternative to the traditional opal. The gem’s appeal lies in its breathtaking beauty and impressive range of pink hues. Pink tourmaline crystals form in distinctive prism-like structures, displaying remarkable beauty when exposed to light. The gem contains a diverse variety of elements, primarily elbaite. Its versatility in color, ranging from delicate blush tones to vibrant magenta, makes it a popular choice for jewelry. The story of Empress Tzu-Hsi’s passion for pink tourmaline further elevates its historical significance.
Opal: The Iridescent Beauty
Opal, the original October birthstone, continues to captivate with its unique play-of-color. This phenomenon, caused by the diffraction of light through microscopic silica spheres, creates a kaleidoscope of hues that shift with the light and angle. The name “opal” itself reflects this characteristic, originating from the Greek word “Opallos,” meaning a shift in color. The dramatic play-of-color has inspired comparisons to fireworks, galaxies, and volcanic sunsets. The value of an opal is significantly influenced by the intensity and range of its play-of-color, with black opals being the rarest and most precious.
October and Libra: A Symbolic Connection
The month of October is associated with the zodiac sign Libra, represented by the scales. Libras are believed to value balance, harmony, and diplomacy, and the dual birthstones of October – opal and tourmaline – reflect this appreciation for options and variety. Both gemstones offer a mix of bold colors and interesting qualities, catering to the Libra’s desire for aesthetic appeal and harmonious balance.
Conclusion
Opal and pink tourmaline, the dual birthstones of October, represent a captivating blend of history, beauty, and symbolism. Opal, with its ancient lore and iridescent play-of-color, remains a cherished traditional birthstone. Pink tourmaline, a more recent addition, offers a vibrant and modern alternative, steeped in its own fascinating history. Whether one prefers the ethereal beauty of opal or the captivating hues of pink tourmaline, both gemstones offer a meaningful and stunning way to celebrate an October birthday.
