October boasts not one, but two recognized birthstones: pink tourmaline and opal. Both gemstones offer a captivating array of colors and possess unique histories, making them cherished choices for those born in the tenth month. This article will delve into the origins, characteristics, and significance of these beautiful October birthstones.
History and Lore
Opal, the traditional October birthstone, has a rich and storied past. Its name is believed to originate from the Sanskrit word “upala,” meaning “precious stone,” brought to the Western world from India. The Romans referred to it as opalus. Throughout history, opal has inspired a wealth of folklore and symbolism. Ancient Bedouins believed opals contained lightning and fell from the sky during thunderstorms, while ancient Greeks associated the stone with prophecy and protection from disease. Europeans once considered opal a symbol of purity, hope, and truth, believing it embodied the virtues of all colored stones. It is also traditionally given to celebrate the 14th wedding anniversary.
Pink tourmaline, the modern October birthstone, also carries historical weight. In the late 19th century, the gemstone captured the attention of the Chinese Empress Dowager Tzu-Hsi, who became so enamored with its beauty that she acquired nearly the entire production from a California mine. She continued to cherish pink tourmaline even after her death, being buried with a pillow of the gemstone, and the remainder of her collection was crafted into exquisite carvings.
In more recent history, the National Association of Jewelers officially recognized pink tourmaline as an October birthstone in 1912, offering an alternative to opal. Other gemstones, including aquamarine, jasper, and coral, are also considered October birthstones in certain cultures, with aquamarine and beryl used in ancient times, jasper favored in Tibet, and coral popular in India.
Geological Formation and Sources
Opal’s formation is a fascinating geological process. It arises from a combination of silica and water that flows into cracks and spaces within the ground, gradually hardening and solidifying over millions of years. Opal can be found in several locations worldwide, including Australia, Ethiopia, Brazil, and parts of the United States.
Pink tourmaline forms in distinctive prism-like crystals with long hexagonal structures. These crystals exhibit remarkable beauty when exposed to light. While the sources for pink tourmaline are not explicitly detailed in the provided materials beyond a mention of a California mine historically supplying the Empress Dowager Tzu-Hsi, tourmaline in general occurs in a variety of geological environments.
Gemological Properties
Pink tourmaline is known for its breathtaking beauty and impressive range of pink hues. It contains a diverse variety of elements and typically consists primarily of the mineral elbaite. The gemstone can even display multiple colors within a single crystal, known as watermelon tourmaline.
Opal is particularly valued for its “play-of-color,” a shifting display of rainbow hues. This phenomenon is what sets opal apart and has been likened to fireworks, galaxies, and volcanoes. Precious opal ranges in color from clear to white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, brown, and black. Red opal against a black background is considered the rarest and most valuable. White and green opals are the most commonly found.
