Individuals born on December 28th are graced with a birthstone that embodies both beauty and a relatively recent discovery in the world of gemstones: Tanzanite. This mesmerizing gem, celebrated for its vibrant hues and rich symbolism, has quickly become a coveted treasure, particularly for those born in the final days of the year. This article will delve into the history, geological origins, gemological properties, and significance of Tanzanite, offering a comprehensive overview of this remarkable December birthstone.
History and Lore
Tanzanite is a newcomer to the realm of established gemstones, with its discovery occurring only in 1967 in the foothills of Mount Kilimanjaro in Tanzania. Unlike many birthstones steeped in centuries of lore, Tanzanite’s history is comparatively brief. However, this has not diminished its appeal or the meanings attributed to it. While lacking the extensive historical narratives of rubies or emeralds, Tanzanite has rapidly acquired associations with spiritual awareness, deep meditation, and psychic abilities. Some believe the gem can activate the throat, third-eye, and crown chakras, facilitating communication with higher dimensions and promoting self-transformation.
The name “Tanzanite” was officially adopted by Tiffany & Co. after its discovery, recognizing its Tanzanian origin and capitalizing on the gem’s inherent beauty. The gem’s introduction to the market was a deliberate branding effort, and it quickly gained popularity as a sophisticated and elegant gemstone.
Geological Formation and Sources
The unique geological conditions required for Tanzanite formation contribute to its rarity. It is found in only one location worldwide: the Merelani Hills of northern Tanzania, near Mount Kilimanjaro. This limited geographical source significantly impacts its value and desirability. Tanzanite forms within a specific type of metamorphic rock, created by intense heat and pressure.
The gem’s formation is linked to the complex geological history of the region, involving the collision of tectonic plates and the subsequent metamorphism of existing rocks. The rarity of this specific geological environment explains why Tanzanite is not found anywhere else on Earth.
Gemological Properties
Tanzanite is a blue-violet variety of the mineral zoisite, a calcium aluminum silicate. Its chemical formula is Ca₂Al₃(SiO₄)₃(OH). The gem exhibits strong trichroism, meaning it displays three different colors – blue, violet, and burgundy – depending on the viewing angle. This optical phenomenon contributes to its captivating appearance and requires skilled cutting to maximize the desired blue and violet hues.
Here's a summary of Tanzanite’s key gemological properties:
| Property | Value |
|---|---|
| Chemical Formula | Ca₂Al₃(SiO₄)₃(OH) |
| Color | Blue, Violet, Burgundy |
| Hardness (Mohs) | 6.5 - 7 |
| Specific Gravity | 6.7 - 6.8 |
| Refractive Index | 1.619 - 1.688 |
| Crystal System | Triclinic |
Tanzanite’s hardness of 6.5 to 7 on the Mohs scale makes it relatively durable, but still susceptible to scratches and damage from impacts. It requires careful handling and appropriate settings in jewelry to protect its surface. Heat treatment is commonly used to enhance Tanzanite’s blue color, removing the brownish tones often present in rough stones. This treatment is stable and permanent, and is widely accepted within the gem trade.
Symbolism and Metaphysical Beliefs
Beyond its aesthetic appeal, Tanzanite is imbued with symbolic meanings. It is associated with transformation, communication, and spiritual growth. The gem is believed to encourage self-awareness and facilitate a deeper understanding of one’s purpose. Its connection to the throat chakra is thought to enhance communication skills and promote honest expression.
The association with the third-eye chakra suggests that Tanzanite can stimulate intuition and psychic abilities. Some practitioners use Tanzanite in meditation to access higher states of consciousness and gain insights into the spiritual realm. The gem is also linked to healing, protection, and the release of negative energy.
Care and Cleaning
Due to its moderate hardness, Tanzanite requires careful handling and cleaning. It is susceptible to scratches from harder materials and can be damaged by ultrasonic cleaners or harsh chemicals. The recommended cleaning method involves using warm, soapy water and a soft brush. Rinse thoroughly and dry with a soft cloth.
Avoid exposing Tanzanite to sudden temperature changes or prolonged sunlight, as this can affect its color. It is advisable to have Tanzanite jewelry professionally cleaned and inspected periodically to ensure its continued beauty and structural integrity. Proper care will ensure that Tanzanite jewelry remains as radiant and beautiful as the day it was acquired.
December Birthstone Variations
While Tanzanite is prominently featured as a December birthstone, it shares this honor with other gems. Turquoise and Blue Zircon are also officially recognized as December birthstones, with Blue Topaz often listed as an alternative. The association of multiple birthstones with a single month allows individuals to choose a gem that resonates with their personal preferences and beliefs. Turquoise, with its long history and connection to protection and good fortune, offers a contrasting aesthetic and symbolic meaning to the more modern Tanzanite. Blue Zircon, known for its brilliance and fire, provides another captivating option for those born in December.
The Significance of December 28th
For those specifically born on December 28th, Tanzanite holds a particularly special significance. It is considered the primary birthstone for this date, embodying the qualities and energies associated with both the gem itself and the Capricorn zodiac sign, which begins on December 22nd. Capricorns are known for their responsibility, self-control, and ambition, qualities that align with Tanzanite’s association with transformation and purpose. The combination of the gem’s metaphysical properties and the zodiac sign’s characteristics creates a unique and powerful symbolism for individuals born on this day.
Conclusion
Tanzanite stands as a testament to the beauty and wonder of the natural world. Its captivating color, unique geological origins, and relatively recent discovery have cemented its place as a highly sought-after gemstone. For those born on December 28th, Tanzanite is more than just a birthstone; it is a symbol of individuality, transformation, and spiritual awareness. Its enduring appeal and timeless beauty make it a cherished companion, encapsulating the essence of those who celebrate their birthdays under its radiant glow.
