History and Lore
The history of pink tourmaline is deeply intertwined with cultural legends and notable historical figures, particularly in the late 19th century. A pivotal chapter in its story involves Chinese Empress Dowager Tzu-Hsi, who developed an intense passion for the gemstone in the late 1800s. According to historical accounts, her affinity was so profound that she purchased nearly the entire production from a California mine. Her devotion to pink tourmaline extended beyond her lifetime; it is recorded that she was laid to rest on a pink tourmaline pillow, and her extensive collection was later transformed into exquisite carvings. This historical episode underscores the gemstone's high value and desirability during that era, establishing its reputation among the elite.
Ancient beliefs also attributed special powers to tourmaline. In Egyptian lore, the stone was believed to have been created in the Earth's depths before ascending toward the sun, passing through a rainbow on its journey. This mythical passage was thought to have imbued the stones with their diverse array of colors. Furthermore, ancient mystics and cultures believed that the gemstone's dazzling variety could inspire artistic expression and creativity. A more specific belief associated with pink tourmaline, noted in some sources, is its historical use for calming emotions and inspiring feelings of kindness, a lore that aligns with its modern symbolism of compassion and emotional healing.
The journey of pink tourmaline to its status as a modern birthstone is part of a broader historical evolution. The concept of birthstones can be traced back to the Breastplate of Aaron described in the Old Testament, which featured twelve gemstones representing the twelve tribes of Israel. Over centuries, this tradition evolved, with different cultures and organizations proposing various lists. The modern list, largely standardized in the early 20th century, was adopted by the American National Association of Jewelers (now Jewelers of America) in 1912. Pink tourmaline was officially recognized as the modern birthstone for October during this standardization, providing a vibrant and accessible alternative to the more traditional, and often more fragile, opal.
Geological Formation and Sources
Pink tourmaline is a complex borosilicate mineral that forms deep within the Earth's crust. Its pink coloration is attributed to the presence of specific trace elements during its formation, primarily manganese and lithium. These elements become incorporated into the mineral's crystal structure as it crystallizes from hot, mineral-rich fluids that permeate fractures and cavities in the surrounding rock. The primary host rocks for tourmaline are granite and pegmatite, which are coarse-grained igneous rocks formed from the slow cooling of magma. It is common to find pink tourmaline occurring alongside other minerals such as quartz, mica, and feldspar, often forming breathtaking natural clusters that are prized by mineral collectors.
The crystal habit of pink tourmaline is distinctive, typically forming as long, prismatic, hexagonal crystals. These well-formed crystals can exhibit a remarkable beauty and clarity when cut and polished for use in jewelry. The elbaite variety is the most common type of tourmaline found in jewelry, and pink tourmaline is predominantly composed of this mineral species.
Pink tourmaline is sourced from several key mining regions across the globe, each contributing to the global supply of this gemstone. The most significant sources include: - Brazil: A leading producer of tourmaline, offering a wide range of colors and qualities. - Nigeria: Known for producing vibrant pink tourmaline crystals. - Mozambique: A source of high-quality pink and red tourmaline. - Various regions of West Africa: Contribute to the supply of this gemstone. - California, United States: Historically significant, as the source of the tourmaline that captivated Empress Dowager Tzu-Hsi.
The availability of pink tourmaline from these diverse locations helps ensure its presence in the gemstone market, making it a relatively accessible birthstone for October-born individuals.
Gemological Properties
Understanding the physical and optical properties of pink tourmaline is essential for gemologists, jewelers, and consumers alike. These characteristics determine the stone's durability, appearance, and value.
Color and Variety: Pink tourmaline showcases a striking pink hue with numerous variations throughout the color spectrum, ranging from delicate pastel blushes to deep, saturated rose and raspberry tones. This wide range of color allows for significant diversity in jewelry design. Some tourmaline crystals even form with multiple colors, most famously the "watermelon tourmaline," which displays a green rind and a pink core, a unique and sought-after variety. Tourmalines with more raspberry or purple tones are often classified as rubellite, a term sometimes used interchangeably with pink tourmaline but typically referring to the more deeply saturated red-pink varieties. It is important to note that while the pink variety is most commonly used to represent October’s birthstone, the broader tourmaline family includes a vast array of colors, such as green ("chrome" tourmaline) and the exceptionally rare and valuable neon blue-green "Paraiba" tourmaline, which is prized for its traces of copper.
Hardness and Durability: On the Mohs scale of mineral hardness, pink tourmaline measures between 7 and 7.5. This level of hardness makes it quite durable for everyday wear in jewelry, as it is resistant to scratching from most common substances (a copper penny has a hardness of about 3, and a steel knife blade is about 5.5). However, despite its good hardness, it is not impervious to damage. It can be chipped or fractured if struck with sufficient force against a hard surface. Furthermore, pink tourmaline is susceptible to damage from excessive heat, which can cause permanent color change or structural harm. Therefore, it is advisable to avoid exposing pink tourmaline jewelry to high temperatures, such as those found in a jeweler's torch during repairs, without proper precautions.
Clarity and Inclusions: Like many gemstones, pink tourmaline can contain inclusions, which are internal features that are natural to the mineral. The presence, type, and visibility of inclusions affect the gemstone's clarity grade and, consequently, its value. While some inclusions are accepted, especially in colored stones, overly included material may be less desirable for fine jewelry. The gem's clarity is often assessed based on eye-cleanliness, meaning the absence of inclusions visible to the unaided eye.
Cut and Carat Weight: Pink tourmaline is faceted into a variety of shapes to maximize its color and brilliance. The choice of cut often depends on the crystal's shape and the desired final appearance. Common cuts include oval, cushion, round, and emerald cuts. The gemstone's good hardness makes it suitable for intricate faceting. As for carat weight, pink tourmaline is available in a wide range of sizes. Smaller specimens are more affordable, while top-quality crystals of larger sizes can command significant prices, especially for fine rubellite or exceptional pink hues.
