The December 28th Birthstone: Tanzanite
Tanzanite is the designated birthstone for those born on December 28th. Its discovery in the 1960s in the foothills of Mount Kilimanjaro in Tanzania marked a significant event in the world of gemstones. Unlike many other gemstones that have been known for centuries, Tanzanite is a relatively modern addition to the birthstone calendar. This gem has quickly gained popularity due to its unique color and its association with spiritual growth and transformation.
Tanzanite is celebrated for its radiant hues, which range from deep violet-blue to rich purple. Its color-changing properties make it a particularly intriguing gemstone, as it can appear different under various lighting conditions. This characteristic is due to the gemstone's pleochroism, a property that allows it to display multiple colors depending on the angle from which it is viewed.
History and Lore
The history of Tanzanite is relatively short compared to other gemstones, but it is rich in significance. Discovered in the 1960s in Tanzania, this gemstone was named after its country of origin. Its discovery was a remarkable event, as it was found in a single location, making it one of the few gemstones that cannot be found anywhere else in the world. This exclusivity has contributed to its allure and value.
Tanzanite quickly became a symbol of transformation and new beginnings. In the context of birthstones, it is believed to resonate with the qualities of individuals born on December 28th. These individuals are often seen as having the potential to undergo significant personal growth and to embrace new opportunities. The symbolism of Tanzanite as a stone of spiritual awareness and intuition aligns with these traits.
The gemstone's association with spiritual growth is further reinforced by its connection to the third eye chakra. This chakra is believed to be the center of intuition and insight, and Tanzanite is thought to enhance these qualities. For individuals born on December 28th, wearing Tanzanite is believed to support their journey of self-discovery and inner growth.
Geological Formation and Sources
Tanzanite is a variety of the mineral zoisite, which is part of the epidote group of minerals. Its chemical formula is Ca₂Al₃(SiO₄)(Si₂O₇)O(OH) and it is primarily composed of calcium, aluminum, silicon, and oxygen. The gemstone's unique color is due to the presence of vanadium, which is a trace element that causes the blue and violet hues.
The formation of Tanzanite is closely tied to the geological conditions of Tanzania. The gemstone is found in a specific area of the country, in the foothills of Mount Kilimanjaro. This region is characterized by metamorphic rocks, which are formed under high pressure and temperature conditions. The combination of these geological factors has resulted in the formation of Tanzanite, making it one of the most unique gemstones in the world.
The rarity of Tanzanite is due to its limited source. Unlike other gemstones that can be found in multiple locations around the world, Tanzanite is only found in Tanzania. This exclusivity has made it a highly sought-after gemstone, particularly among collectors and jewelry enthusiasts. The limited supply of Tanzanite has also contributed to its value, as it is considered a rare and precious gemstone.
Gemological Properties
Tanzanite possesses a range of gemological properties that make it a distinctive and valuable gemstone. One of the most notable characteristics of Tanzanite is its pleochroism. This means that the gemstone can display different colors when viewed from different angles. Tanzanite typically exhibits a range of colors, including deep violet, blue, and purple. This property is a result of the way light interacts with the gemstone's internal structure.
The hardness of Tanzanite is another important gemological property. On the Mohs scale of mineral hardness, Tanzanite has a rating of 6 to 7. This means that it is relatively soft compared to other gemstones, such as diamonds, which have a hardness of 10. Due to its lower hardness, Tanzanite requires special care to prevent scratches and damage. It is also important to avoid exposing Tanzanite to harsh chemicals or extreme temperatures, as this can affect its appearance and durability.
The refractive index of Tanzanite is another key gemological property. The refractive index measures how much light is bent as it passes through a gemstone. Tanzanite has a refractive index of 1.69 to 1.71, which contributes to its brilliance and sparkle. The gemstone's high refractive index is one of the reasons why it is so visually appealing, as it allows it to reflect light in a way that enhances its color and clarity.
Tanzanite is also known for its transparency. High-quality Tanzanite is typically transparent, with minimal inclusions or imperfections. However, some Tanzanite may contain minor inclusions, which can affect its clarity. The presence of inclusions can also impact the gemstone's value, as clearer Tanzanite is generally more desirable.
Symbolism and Metaphysical Beliefs
Tanzanite is associated with a range of symbolic meanings and metaphysical beliefs, particularly in the context of birthstones. For individuals born on December 28th, Tanzanite is believed to enhance spiritual awareness and intuition. The gemstone is thought to open the third eye chakra, which is associated with insight and inner vision. This makes Tanzanite a powerful tool for meditation and self-discovery.
In addition to its spiritual properties, Tanzanite is also believed to promote emotional healing and balance. The gemstone is associated with the ability to transform negative emotions into positive ones, making it a valuable tool for individuals seeking to overcome challenges and grow as a person. Tanzanite is also believed to support the process of forgiveness and self-acceptance, helping individuals to move forward from past experiences.
The symbolism of Tanzanite as a stone of transformation and new beginnings is particularly relevant for those born on December 28th. This date marks the end of December and the beginning of the new year, making it a time of reflection and renewal. Tanzanite is believed to support this process of transformation, helping individuals to embrace new opportunities and experiences.
Care and Cleaning
Due to its relatively low hardness and sensitivity to certain conditions, Tanzanite requires careful handling and cleaning to maintain its beauty and durability. One of the most important aspects of Tanzanite care is to avoid exposure to harsh chemicals. These can cause damage to the gemstone's surface and affect its appearance. It is recommended to use mild, soapy water and a soft cloth to clean Tanzanite jewelry.
Tanzanite should also be protected from extreme temperatures, as this can cause it to become brittle or lose its color. It is important to store Tanzanite jewelry in a cool, dry place, away from direct sunlight and heat sources. Storing Tanzanite separately from other gemstones can also help prevent scratches and damage.
When wearing Tanzanite jewelry, it is important to be mindful of activities that could potentially cause damage. For example, Tanzanite should not be worn during activities that involve heavy physical contact or exposure to abrasive materials. It is also advisable to avoid wearing Tanzanite during activities that involve exposure to saltwater or chlorine, as these can have a negative impact on the gemstone.
Professional cleaning and inspection are also recommended for Tanzanite jewelry. Jewelers who specialize in gemstone care can provide expert advice on the best ways to clean and maintain Tanzanite. Regular inspections can help identify any potential issues, such as loose settings or damage to the gemstone, and ensure that the jewelry remains in good condition.
