For those born on December 29th, Tanzanite holds the esteemed position of birthstone, a gemstone celebrated for its captivating beauty and relatively recent discovery. This gem, characterized by its exquisite blue-violet hues, has quickly become a favorite among gem enthusiasts and jewelry designers alike. This article will delve into the history, meaning, gemological properties, and significance of Tanzanite as the birthstone for December 29th.
History and Lore
Tanzanite’s story is unique among birthstones, as it was only discovered in the late 1960s in the Merelani Hills of northern Tanzania, near Mount Kilimanjaro. This makes it one of the newest birthstones recognized in modern times. Prior to its discovery, the gem was largely unknown, lacking the centuries of lore and tradition associated with older gemstones like turquoise or zircon. However, its striking color and rarity quickly propelled it to prominence.
While lacking ancient historical ties, Tanzanite has rapidly acquired symbolic meaning. It is considered a stone of transformation, spiritual growth, and enlightenment. Its association with December, a month often linked to introspection and the winter solstice, further enhances its symbolic resonance. The gem’s emergence in the late 20th century also lends it a modern appeal, representing new beginnings and a connection to the present.
Geological Formation and Sources
Tanzanite is a variety of the mineral zoisite, a calcium aluminum silicate. Its unique blue-violet color is attributed to the presence of vanadium within its crystal structure. The gem’s formation requires a specific geological environment, making its occurrence exceptionally rare. It is found in a relatively small area – the Merelani Hills in Tanzania – making Tanzania the sole commercial source of this gemstone. This limited geographic origin contributes significantly to its value and desirability.
The geological processes that created Tanzanite are complex, involving metamorphic activity and the presence of specific trace elements. The gem forms within rocks that have undergone intense heat and pressure, resulting in the crystallization of zoisite. The presence of vanadium during this process is crucial for developing the characteristic blue-violet color.
Gemological Properties
Tanzanite exhibits several notable gemological properties that contribute to its allure. Its color ranges from deep indigo to vibrant violet-blue, with the most desirable stones displaying a strong, saturated hue. A key characteristic of Tanzanite is its pleochroism, meaning it displays different colors when viewed from different angles. This phenomenon results in flashes of blue, violet, and sometimes even burgundy, adding depth and dimension to the gem.
Here's a summary of Tanzanite's key properties:
| Property | Description |
|---|---|
| Mineral | Zoisite (Calcium Aluminum Silicate) |
| Color | Blue to Violet-Blue |
| Pleochroism | Displays different colors from angles |
| Hardness (Mohs) | 6.5 - 7 |
| Crystal System | Triclinic |
| Refractive Index | 1.619 – 1.672 |
| Specific Gravity | 3.35 – 3.50 |
Tanzanite’s hardness of 6.5 to 7 on the Mohs scale makes it relatively durable, but it requires careful handling to avoid scratches or damage. It is also sensitive to heat, and prolonged exposure to high temperatures can cause color loss.
Symbolism and Metaphysical Beliefs
Tanzanite is deeply associated with spiritual growth, enlightenment, and a heightened sense of intuition. It is believed to stimulate the throat and third eye chakras, promoting clear communication and a deeper connection to one’s inner self. The gem’s calming blue tones are thought to foster a sense of tranquility and emotional balance.
Beyond these general metaphysical properties, Tanzanite is also linked to transformation and positive change. It is believed to help individuals release old patterns and embrace new possibilities. Some believe it can enhance psychic abilities and facilitate spiritual journeys. The stone’s association with wisdom and clarity makes it a valuable tool for those seeking guidance and understanding.
Care and Cleaning
Due to its moderate hardness, Tanzanite requires careful handling and cleaning. It is susceptible to scratches from harder materials, so it should be stored separately from diamonds and other abrasive gemstones. Cleaning Tanzanite is best done with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, as these can damage the gem.
Given its sensitivity to heat, Tanzanite should not be exposed to prolonged sunlight or high temperatures. It is also advisable to have Tanzanite jewelry professionally inspected and cleaned periodically to ensure its continued beauty and integrity.
December Birthstones: A Broader Perspective
While Tanzanite is specifically highlighted as the birthstone for December 29th, December is unique in having multiple recognized birthstones. Traditionally, turquoise and zircon were considered the primary December birthstones, representing the cool, serene colors of winter. More recently, blue topaz and lapis lazuli have also been added to the list, offering a diverse range of choices in color, price, and personal meaning.
The inclusion of multiple birthstones for December allows individuals to select a gem that resonates with their personal preferences and beliefs. Each stone carries its own unique history, symbolism, and aesthetic qualities, providing a rich tapestry of options for those born in this month. The variety also caters to different tastes and budgets, ensuring that everyone can find a December birthstone that suits them.
