December boasts a remarkable array of birthstones, offering a spectrum of blue hues to reflect the winter season. While turquoise and blue topaz are also associated with the month, Tanzanite and Zircon stand out as particularly significant gems, each with a unique history, geological origin, and symbolic meaning. This article will delve into the characteristics of these two December birthstones, exploring their historical context, gemological properties, and cultural significance, with a particular focus on their relevance to those born on December 22nd, falling under the Capricorn zodiac sign.
A History Intertwined with Tradition and Discovery
The tradition of associating gemstones with specific months and zodiac signs dates back centuries. Ancient civilizations believed that wearing the correct stone could bestow powers and bring good fortune. While the concept has evolved, the practice of honoring one’s birth month with a gemstone remains popular today. Turquoise has a long-standing history as a December birthstone, cherished for centuries, while Tanzanite is a relatively recent discovery, unearthed in Tanzania in 1967. Zircon, too, has a long history of use, being one of the oldest minerals on Earth.
The practice of assigning multiple birthstones to a single month reflects a desire to offer a wider range of choices in color, price, and personal meaning. December, with its diverse selection of gems, caters to different tastes and histories.
Geological Formation and Sources
Zircon is celebrated as one of the oldest minerals on Earth, indicating its formation occurred over vast geological timescales. Its origins are diverse, found in various igneous, metamorphic, and sedimentary rocks. The sources for zircon are widespread, though specific locations are not detailed in the provided materials.
Tanzanite, in contrast, is exceptionally rare, found in only one known location: the Merelani Hills of northern Tanzania, near Mount Kilimanjaro. This limited source contributes to its exclusivity and value. The gem’s formation is linked to the complex geological processes occurring in this region.
Gemological Properties: Zircon’s Fire and Tanzanite’s Pleochroism
Zircon is known for its brilliant fire and a rainbow of colors, though the blue variety is particularly favored as a December birthstone. The sources do not provide specific details regarding its chemical composition or refractive index. However, it is noted for its clarity and color range, sometimes even resembling diamonds in its sparkle.
Tanzanite is highly prized for its unique blue to violet color. This color is not uniform, however, and Tanzanite exhibits a phenomenon called pleochroism, meaning it displays different colors when viewed from different angles. This characteristic adds to its allure and complexity. The sources do not provide details on its chemical composition or hardness.
Here's a table summarizing the key properties, based on the provided sources:
| Gemstone | Color(s) | Rarity | Key Feature |
|---|---|---|---|
| Zircon | Blue, golden, red, clear | Common | Brilliant fire, clarity |
| Tanzanite | Blue to violet | Very rare | Pleochroism, unique color |
Symbolism and Metaphysical Beliefs
Both Tanzanite and Zircon are associated with positive attributes. Zircon is valued for its historical and geological significance, representing wisdom and protection. Blue zircon, in particular, is known for its calming energy.
Tanzanite resonates with charisma and is considered a stone of transformation. It is believed to facilitate communication and encourage self-expression. For those born under the Sagittarius zodiac sign (November 22 – December 21), Tanzanite is considered a particularly fitting birthstone, aligning with their energetic and charismatic nature. For Capricorns (December 22 – January 19), the gem offers a sense of joy and energy, potentially relieving stress and burnout.
Turquoise, another December birthstone, carries a soft, sky-blue glow with earthy charm, long cherished by ancient cultures for its spiritual and healing qualities.
Zodiacal Associations and Personal Meaning
The provided sources highlight specific zodiacal associations for December birthstones. Sagittarius (November 22 – December 21) is linked to Tanzanite, while Capricorn (December 22 – January 19) is traditionally associated with Ruby, though zircon is also considered a suitable choice. The sources suggest that individuals born on the cusp of zodiac signs (e.g., December 19-21) may find resonance with the birthstones of both signs.
Choosing a birthstone is a personal experience. The sources emphasize that the variety of options allows individuals to select a gem that resonates with their own tastes and preferences. Whether drawn to the vibrant fire of zircon or the captivating hues of Tanzanite, the December birthstones offer a meaningful way to celebrate one’s birth month.
Care and Cleaning
While the sources do not provide specific care instructions for Tanzanite or Zircon, general gemstone care principles apply. Given their potential for brilliance and clarity, these gems should be protected from scratches and harsh chemicals. Gentle cleaning with warm, soapy water and a soft cloth is recommended. Professional cleaning and inspection are advisable to maintain their luster and integrity.
The Allure of Blue: A December Palette
The prevalence of blue hues among December birthstones – turquoise, blue zircon, blue topaz, and Tanzanite – reflects the cool, crisp tones of the winter season. This shared color palette creates a sense of harmony and unity among the gems, while their individual characteristics offer a diverse range of options for those seeking a meaningful birthstone.
Conclusion
December’s birthstones, particularly Tanzanite and Zircon, represent a fascinating blend of history, geology, and symbolism. From the ancient traditions of associating gemstones with zodiac signs to the modern discovery of Tanzanite in Tanzania, these gems offer a rich tapestry of meaning and beauty.
