December 16 is uniquely associated with a trio of gemstones: Tanzanite, Turquoise, and Zircon. Among these, Tanzanite stands out as a relatively modern discovery with a rich history, captivating color, and deep symbolic meaning. This article explores the gemological properties, historical context, and cultural significance of Tanzanite, offering a comprehensive understanding of why it has become an important birthstone for those born on December 16.
Tanzanite is celebrated not only for its stunning violet-blue hues but also for its rarity and the transformative symbolism it carries. As a gemstone of spiritual enlightenment, communication, and protection, it appeals to both gemstone enthusiasts and those who seek meaningful jewelry. Its exclusive origin in Tanzania adds to its allure, making it a unique and valuable addition to the world of gemology.
History and Lore
Tanzanite was discovered in the 1960s in the Merelani Hills of Tanzania, near the base of Mount Kilimanjaro. This makes it one of the few gemstones with a very recent origin in the world of gemology. The gemstone was named after its country of origin, Tanzania, and quickly gained popularity for its unique color and metaphysical properties.
The discovery of Tanzanite is attributed to a Maasai tribesman who found the rough material in the 1960s. However, the stone’s significance as a gemstone was not fully realized until it was cut and polished by a British gem cutter, who noted its remarkable violet-blue color. This transformation of the raw material into a dazzling gemstone marked the beginning of Tanzanite's journey into the global gemstone market.
Tanzanite is also believed to have been known to the local population for centuries, but it was only when the stone was properly cut and marketed that its true value was recognized. As a relatively new gemstone, Tanzanite does not carry the same ancient lore as some other birthstones. However, its modern symbolism and metaphysical properties have quickly made it a cherished gemstone among those who wear it.
Geological Formation and Sources
Tanzanite is a variety of the mineral zoisite, with the chemical formula Ca₂Al₃(SiO₄)(OH)₃·(OH). Its color is due to trace amounts of vanadium, which are responsible for the violet-blue hues that make Tanzanite so distinctive. The stone is formed under high pressure and temperature conditions deep within the Earth's crust. Specifically, it is found in metamorphic rock formations, where the unique geological conditions of Tanzania have allowed for the creation of this rare gemstone.
Tanzanite is exclusively found in Tanzania, which is why it is considered a national treasure. The Merelani Hills, where the gemstone is mined, are the only known source of Tanzanite in the world. This exclusivity adds to the stone's desirability and value. The mining of Tanzanite is a carefully managed process, with strict regulations in place to ensure sustainable practices and the protection of the environment.
The geological rarity of Tanzanite is further emphasized by the fact that the supply is expected to diminish over time. This has led to concerns about the future availability of high-quality Tanzanite, making it a gemstone that is both valuable and increasingly precious.
Gemological Properties
Tanzanite is known for its vibrant color and unique optical properties. It has a hardness of 6 to 6.5 on the Mohs scale, which means it is relatively soft compared to other gemstones such as diamonds or sapphires. This low hardness makes Tanzanite more susceptible to scratches and damage, so it requires careful handling and appropriate care to maintain its beauty.
The refractive index of Tanzanite ranges from 1.69 to 1.71, which contributes to its brilliance and luster. The stone is pleochroic, meaning it exhibits different colors when viewed from different angles. This property is one of the reasons why Tanzanite is so captivating; it can appear as a deep blue, a vibrant violet, or a combination of both, depending on the lighting conditions and the orientation of the stone.
Tanzanite is typically cut in a way that maximizes its color and brilliance. The most common cuts include the oval, cushion, and emerald cuts, which help to enhance the gemstone’s natural beauty. The color of Tanzanite can vary depending on the quality and the specific cut, with the most desirable stones displaying a rich, even coloration.
In terms of clarity, Tanzanite is often included, with visible inclusions that are characteristic of the gemstone. These inclusions are not considered flaws but rather part of the stone’s natural beauty. High-quality Tanzanite is characterized by a clean, even color and minimal inclusions that do not detract from its overall appearance.
Symbolism and Metaphysical Beliefs
Tanzanite is associated with a range of symbolic meanings and metaphysical properties that have made it a popular choice for those born on December 16. One of the most significant aspects of Tanzanite is its connection to spiritual enlightenment and transformation. The gemstone is believed to open the third eye, enhancing intuition and promoting a deeper understanding of oneself and the world.
In addition to its spiritual properties, Tanzanite is also linked to communication and self-expression. The vibrant blue hues of the gemstone are thought to stimulate clear communication and encourage individuals to articulate their thoughts and emotions effectively. This makes Tanzanite an ideal stone for those who wish to improve their communication skills in both personal and professional settings.
Tanzanite is also revered for its ability to facilitate transformation and change. Those born on December 16 may find that this gemstone encourages personal growth, helping them navigate life's transitions with grace and resilience. This transformative energy is particularly valuable for individuals undergoing significant changes in their lives, as it provides the support and guidance needed to embrace new beginnings.
Another important aspect of Tanzanite is its protective and healing properties. In metaphysical beliefs, Tanzanite is considered a protective stone that dispels negative energies and promotes physical and emotional well-being. It is believed to shield the wearer from harmful influences and to provide a sense of security and calm. This makes Tanzanite an ideal gemstone for those who seek comfort and protection in their daily lives.
Care and Cleaning
Due to its relatively low hardness, Tanzanite requires special care to maintain its beauty and durability. The gemstone should be stored separately from other gemstones to prevent scratches and damage. Tanzanite is also sensitive to heat and direct sunlight, so it should be kept in a cool, dark place when not in use.
When cleaning Tanzanite, it is important to use gentle methods to avoid damaging the stone. A soft cloth and mild soap and water solution are recommended for cleaning. Ultrasonic cleaners and steam cleaners should be avoided, as they can potentially damage the gemstone. Tanzanite should also be removed before engaging in activities that may expose it to harsh chemicals or physical impact.
When setting Tanzanite in jewelry, it is important to choose a secure and appropriate setting that provides adequate support for the gemstone. The softness of Tanzanite means that it can be more prone to chipping or breaking if not properly protected. A well-designed setting can help to minimize the risk of damage and ensure that the gemstone remains in excellent condition.
