Tanzanite, a captivating gemstone displaying shades of blue and violet, is prominently featured as a modern birthstone for December, alongside blue zircon. This relatively recent discovery has quickly gained popularity for its exceptional brilliance, unique optical phenomenon known as pleochroism, and the symbolism associated with spiritual awareness and manifestation. While traditionally December was associated with turquoise or lapis lazuli, tanzanite has emerged as a favored choice, celebrated for its beauty and the intriguing story behind its origin. This article will delve into the history, geological formation, gemological properties, symbolism, and care of this remarkable gemstone.
History and Lore
Though a relatively new addition to the world of gemstones, tanzanite’s story is rich with discovery and recognition. Initially named “Blue Zoisite” upon its finding, the stone was later renamed “Tanzanite” in honor of Tanzania, its sole known origin. This renaming was a strategic marketing decision intended to capitalize on the gem’s exotic locale and enhance its appeal. The gem’s introduction to the market was facilitated by Tiffany & Co., who recognized its potential and skillfully promoted it to a wider audience.
The practice of assigning gemstones to specific months dates back centuries, with ancient cultures attributing poetic meanings and purported luck to various gems. The modern birthstone list, established in the early 20th century, supplemented the traditional list, offering individuals a broader range of choices. Today, people often select between modern and ancient birthstones, or even consult alternative lists based on astrological signs. Tanzanite’s inclusion as a December birthstone reflects this evolving tradition. Beyond its association with December, tanzanite is also recognized as a traditional gift for a 24th wedding anniversary.
Geological Formation and Sources
Tanzanite is exceptionally rare, found in a very limited geographical area – the Merelani Hills of northern Tanzania. This singular origin contributes significantly to its value and desirability. The gemstone is a blue-violet variety of the mineral zoisite, a calcium aluminum silicate. Its formation is linked to complex geological processes involving metamorphic activity and the presence of vanadium, which contributes to its distinctive color.
The gem’s discovery was relatively recent, and its limited source continues to influence its market availability. The area where tanzanite is found is small, estimated to be only a few square kilometers, making it a finite resource. This scarcity adds to the allure and investment potential of this December birthstone.
Gemological Properties
Tanzanite is prized for its vibrant color, which ranges from deep sapphire blue to a vibrant violet-blue, sometimes exhibiting hints of red. This color variation is a result of its pleochroism, a phenomenon where the gem displays different colors when viewed from different angles. This optical effect adds to its captivating beauty and makes each stone unique.
While specific gemological data like refractive index and chemical formula are not provided in the sources, the sources highlight the importance of color in determining a tanzanite’s value, with rich blue hues being the most sought after. The sources do not provide information on hardness or other detailed gemological properties.
Symbolism and Metaphysical Beliefs
Tanzanite is believed to possess high-vibration healing energy, often described as a “manifestation magnet.” It is associated with spiritual awareness, wisdom, and inner strength. The gem is thought to guide individuals on a path to consciousness and help them navigate challenges with resilience. These metaphysical beliefs contribute to its appeal as a birthstone and a meaningful gift.
The symbolism of birthstones themselves is rooted in the belief that each month, or time of year, influences the characteristics of those born during that period. Gemstones were historically used for healing, protection, and energy renewal, and their meanings continue to hold significance for many. Tanzanite, with its association with wisdom and spiritual growth, embodies these positive attributes.
Care and Cleaning
The provided sources do not offer specific guidance on the care and cleaning of tanzanite. However, given its composition as a silicate mineral, general gemstone care practices would apply. It is advisable to avoid harsh chemicals, ultrasonic cleaners, and extreme temperature changes. Gentle cleaning with warm, soapy water and a soft cloth is recommended to maintain its brilliance. Further research into the specific care requirements of tanzanite is recommended for optimal preservation.
Conclusion
Tanzanite, a relatively recent discovery, has quickly established itself as a captivating and significant gemstone, particularly as a birthstone for December. Its unique color, pleochroism, limited origin, and associated symbolism contribute to its allure. From its humble beginnings as “Blue Zoisite” to its recognition by Tiffany & Co. and its current status as a prized gem, tanzanite’s story is one of discovery, marketing, and enduring beauty. Its association with spiritual awareness and manifestation further enhances its appeal, making it a meaningful and cherished gemstone for those born in December and beyond.
