The tradition of associating gemstones with specific months, and thereby with individuals born in those months, is a practice steeped in history and imbued with symbolic meaning. These “birthstones,” as they are known, are believed to offer luck, protection, and a connection to deeper energies. While the standardization of birthstone lists is a relatively recent phenomenon, dating back to the early 20th century, the practice itself has roots stretching back to ancient civilizations. This article will explore the history and lore surrounding birthstones, with a particular focus on the October birthstone, the captivating opal.
The concept of linking gemstones to specific times of the year originates in ancient times. The breastplate of Aaron, described in the Book of Exodus, featured twelve gemstones representing the tribes of Israel, establishing an early connection between stones and designated groups. Ancient Hindu astrology similarly assigned gemstones to the twelve signs of the zodiac. Over time, this evolved into associating stones with individual months, gaining popularity in 18th-century Poland, where wearing a different gemstone each month was believed to bring good fortune.
The standardization of these lists occurred in 1912, driven by the interests of jewelers seeking to market specific gems. Even today, variations exist, with different cultures and sources offering alternative birthstone assignments. The enduring appeal of birthstones lies in their ability to personalize jewelry and imbue it with meaning, making them treasured gifts and sentimental keepsakes.
The Allure of Opal: A Gemstone of Shifting Colors
October is uniquely represented by two birthstones: opal and tourmaline. However, the opal holds a particularly rich history and captivating allure. Described by the Roman scholar Pliny the Elder as possessing “a softer fire than the ruby,” and exhibiting “the brilliant purple of the amethyst, and the sea green of the emerald – all shining together in incredible union,” the opal is renowned for its play-of-color, a phenomenon that sets it apart from most other gemstones. This iridescent display, where flashes of color shift and change with the angle of light, has made the opal a source of fascination for centuries.
The name “opal” itself is derived from the Greek word “opalus,” meaning “to see a change in color,” a fitting descriptor for this dynamic gem. Throughout history, opals have been prized by various cultures, believed to bring good fortune, good health, and foresight. The Romans considered opals second only to emeralds in value, associating them with hope and purity. Ancient Greeks believed opals granted prophetic powers.
Historical and Literary Significance
The opal’s captivating beauty has inspired writers and artists for generations. It has been referenced in the works of Shakespeare, Ralph Waldo Emerson, Mark Twain, John Steinbeck, and Oscar Wilde, serving as a metaphor for a range of emotions and ideas. Pliny the Elder’s detailed description highlights the opal’s unique optical properties and its esteemed position in Roman society.
Over the past decade, opals have also gained recognition among both antique and modern jewelry collectors, solidifying their status as ideal gems for birthstone jewelry. This increased appreciation reflects a renewed interest in the opal’s unique beauty and historical significance.
Gemological Properties and Formation
While the provided sources do not detail the specific chemical composition or geological formation of opals, they emphasize the gem’s defining characteristic: its play-of-color. This phenomenon is caused by the diffraction of light as it passes through microscopic spheres of silica within the opal. The size and arrangement of these spheres determine the colors that are displayed.
Symbolism and Metaphysical Beliefs
The opal is rich in symbolism, representing foresight, good fortune, hope, and purity. These associations stem from ancient beliefs and have persisted throughout history. The stone is thought to inspire creativity and offer protection. The belief in the opal’s power to bring good luck and positive energy continues to resonate with those who wear it.
