December is a unique month in the world of birthstones, distinguished by a selection of not one, but four recognized gems: blue topaz, turquoise, zircon, and tanzanite. These stones, each possessing a distinct shade of blue, reflect the cool tones of the winter season and offer December-born individuals a diverse range of options to express their individuality. While turquoise holds a long-standing tradition as a December birthstone, and blue topaz is widely popular, tanzanite and blue zircon have also earned their place as recognized gems for those born in the final month of the year. This article will delve into the history, properties, and significance of these December birthstones, with a particular focus on those associated with December 15th: Tanzanite, Turquoise, and Blue Zircon.
A History of December’s Gems
The association of gemstones with specific months dates back centuries, evolving through historical, astrological, and cultural influences. Ruby was once linked to December in ancient times, believed to sharpen the mind and encourage courtly love. Chrysoprase, the old Russian birthstone for December, was thought to bring good fortune and mend broken hearts. Similarly, Onyx held significance as the Tibetan birthstone, offering self-mastery and protective energy, while Bloodstone was a traditional choice, representing courage and vitality.
However, the modern selection of December birthstones underwent changes. Lapis Lazuli was considered a December birthstone prior to the 1950s, representing royalty and self-mastery. Zircon replaced Lapis Lazuli in 1952, and in 2002, Tanzanite was officially added as a December birthstone in the United States. Turquoise, however, has maintained a consistent association with December for thousands of years, valued by ancient shamans as a talisman of protection, prosperity, and luck.
The variety of birthstones for December reflects a desire to provide options based on personal preference, cultural traditions, and budgetary considerations. The addition of newer stones like tanzanite also reflects evolving trends within the gemstone market.
The Allure of Turquoise: A Timeless Tradition
Turquoise, with its soft, sky-blue glow and earthy charm, is arguably the most traditional December birthstone. Its history is deeply rooted in ancient cultures, where it was cherished for its spiritual and healing qualities. For millennia, turquoise has been regarded as a protective talisman, believed to ward off negative energy and bring good fortune.
The stone’s association with December extends back thousands of years, and it continues to be a popular choice for those seeking a connection to ancient traditions. Turquoise is often associated with self-expression and compassion, encouraging open communication and emotional balance.
Tanzanite: A Modern Marvel
Discovered in Tanzania in 1967, Tanzanite is a relatively recent addition to the December birthstone family. This captivating gem is known for its violet-blue shimmer, often reminiscent of sapphire, and exudes an elegant and luxurious vibe. Tanzanite is a highly protective and soothing stone, believed to facilitate the sharing of spiritual information with calm clarity. It is particularly valued for its ability to connect individuals to spiritual sources and enhance meditation practices.
Blue Zircon: A Sparkling Alternative
Blue Zircon, while often overshadowed by its more famous counterparts, is a fascinating and versatile December birthstone. Zircon comes in a variety of colors, including golden, red, and clear, but the blue variety is most frequently associated with December. Blue Zircon is believed to encourage joy and emotional balance, promoting a sense of well-being and inner peace. It can also enhance mental clarity and intuition. While it can sparkle similarly to diamond, it is a distinct gemstone with its own unique properties.
Gemological Properties: A Comparative Overview
While each of these December birthstones possesses unique characteristics, they share a common thread: a captivating blue hue. However, their gemological properties differ significantly.
| Gemstone | Chemical Formula | Color(s) | Hardness (Mohs) |
|---|---|---|---|
| Turquoise | CuAl6(PO4)4(OH)8·4H2O | Sky Blue to Green | 5-6 |
| Tanzanite | Ca2Al3(SiO4)3(OH) | Violet-Blue | 6.5-7 |
| Blue Zircon | ZrSiO4 | Blue | 6.5-7.5 |
Turquoise, a hydrated copper aluminum phosphate, is relatively soft, ranging from 5 to 6 on the Mohs hardness scale. This makes it susceptible to scratching and requires careful handling. Tanzanite, a calcium aluminum silicate hydroxide, exhibits a hardness of 6.5 to 7, making it more durable than turquoise but still requiring protection from abrasion. Blue Zircon, a zirconium silicate, boasts a hardness of 6.5 to 7.5, offering good durability for jewelry wear.
Symbolism and Metaphysical Beliefs
Each December birthstone carries its own unique symbolism and metaphysical properties. Turquoise is associated with protection, healing, and self-expression. Tanzanite is believed to enhance spiritual connection and facilitate clear communication. Blue Zircon is thought to promote joy, emotional balance, and mental clarity.
These beliefs, while not scientifically proven, have been cherished for centuries and continue to resonate with those who seek the energetic properties of gemstones. The stones are often used in meditation practices and worn as talismans to promote well-being and positive energy.
Care and Maintenance
Proper care is essential to maintain the beauty and longevity of December birthstones. Due to its relative softness, turquoise requires gentle handling and should be protected from scratches and harsh chemicals. Tanzanite and Blue Zircon, while more durable, should also be cleaned with mild soap and warm water, avoiding ultrasonic cleaners and harsh abrasives.
Regular cleansing and energizing are also recommended. Bathing the gemstones in full moonlight can help to revitalize their energy, while smudging them with sage or placing them on a piece of selenite can cleanse them of negative vibrations. It is also advisable to remove jewelry containing these gemstones daily, allowing them to rest and avoid potential damage.
