The month of December is uniquely represented in the world of gemstones by a trio of cool, captivating stones: blue topaz, tanzanite, and turquoise. These gems, each with its own distinct character, share a common palette of serene blues and purples that evoke the crisp air and tranquil beauty of winter. As the traditional and modern birthstones for December, they carry deep symbolic meanings and offer a versatile range of options for jewelry enthusiasts. This article delves into the properties, symbolism, and cultural significance of these three December birthstones, drawing from authoritative sources to provide a comprehensive overview for gemstone lovers, jewelry buyers, and students of gemology.
History and Lore: The Path to Modern Birthstones
The concept of birthstones has evolved over centuries, moving from ancient religious and astrological traditions to the standardized lists used today. While the provided sources focus primarily on the modern commercial significance of December birthstones, they hint at a rich tapestry of symbolism and lore that has made these gems beloved for generations.
Blue Topaz, as highlighted in the sources, is traditionally associated with the month of December. Its tranquil hue has long been admired, and modern interpretations link it to symbols of peace, creativity, and optimism. The sources note that blue topaz is also believed to represent wisdom and honesty, adding a layer of intellectual and moral significance to its aesthetic appeal. This aligns with historical beliefs where topaz was often thought to promote clarity of thought and honesty in communication.
Tanzanite, a more recent addition to the gemological world, has quickly gained popularity as a December birthstone. The sources describe it as a stone celebrated for its captivating shades of blue and violet that can appear to shift depending on the light. This mesmerizing color change, known as pleochroism, has contributed to its reputation for radiating positivity and truth. While the sources do not provide ancient historical lore for tanzanite (as it was only discovered in the 20th century), its rapid ascent in popularity speaks to its powerful visual and symbolic impact in modern jewelry culture.
Turquoise, one of the oldest known gemstones, carries a profound historical legacy. The sources mention it as a "lovely shade of blue" that is perfect for December birthstone jewelry, often paired with gold. Although the provided chunks do not detail its ancient history, turquoise has been revered by civilizations worldwide for thousands of years, from the ancient Egyptians to the Native American tribes of the Southwest. It has traditionally been seen as a protective stone, a symbol of good fortune, and a connection to the earth and sky. Its presence in December's birthstone list connects the modern wearer to this ancient stream of cultural significance.
The journey of these stones to their status as December birthstones is largely a product of the modern birthstone list, which was formalized in 1912 by the American National Jewelers' Association (now Jewelers of America). While the provided sources do not explicitly reference this historical event, they present these three gems as the accepted choices for the month, emphasizing their contemporary appeal and symbolic meanings.
Geological Formation and Sources
Understanding the origin of these gems enhances appreciation for their unique characteristics. The provided sources offer some insight into their nature, though detailed geological information is limited.
Blue Topaz is a variety of the mineral topaz, which is a silicate mineral containing fluorine and aluminum. Natural blue topaz is relatively rare; the vibrant blue hues commonly seen in jewelry are typically the result of treating colorless or pale topaz with radiation and heat. The sources describe its color as ranging from "soft sky blue to deep oceanic hues," a spectrum that is largely achieved through these enhancement processes. While the sources do not specify mining locations, topaz is found in various parts of the world, including Brazil, Nigeria, and Sri Lanka.
Tanzanite is a unique gemstone with a single known source. The sources note its "exotic" nature, which is directly linked to its geographic origin. Tanzanite is a variety of the mineral zoisite and is found exclusively in the Merelani Hills of Northern Tanzania, near the base of Mount Kilimanjaro. Its limited geographic occurrence makes it one of the rarest gemstones on Earth. The sources highlight its captivating color range, which is a natural characteristic of the stone, though it is also often heated to enhance its blue tones and improve clarity.
Turquoise is an opaque mineral, a hydrous phosphate of copper and aluminum. Its blue-to-green color is determined by the presence of copper (blue) and iron (green). Turquoise is formed in arid regions where acidic water percolates through rocks containing these minerals. The sources mention its "lovely shades of blue," and while they do not list specific mining locations, turquoise has been historically sourced from regions like Iran (Persia), the Southwestern United States, China, and Tibet. The quality and color of turquoise can vary significantly based on its origin and the presence of its host rock, which often leaves a distinctive matrix pattern.

Turquoise, as an opaque stone, is valued for its uniform color and, in many cases, its attractive matrix patterns.
Symbolism and Metaphysical Beliefs
The allure of gemstones extends beyond their physical beauty into the realm of meaning and belief. The provided sources offer a glimpse into the symbolic attributes associated with each December birthstone.
Blue Topaz is imbued with a sense of calm and clarity. The sources directly state that it "symbolizes peace, creativity, and optimism." This aligns with its cool, serene color, which is often associated with tranquility and open communication. Furthermore, the sources add that blue topaz also symbolizes "wisdom and honesty," making it a stone of truth and intellectual clarity. It is presented as a gem for those who "light up every room they enter," suggesting an aura of positive energy and confidence.
Tanzanite carries a more dynamic and transformative symbolism. The sources describe it as a stone that "radiates positivity and truth." Its unique ability to shift colors in different lights is seen as a metaphor for perspective and adaptability. The exotic and rare nature of tanzanite adds to its mystique, making it a symbol of individuality and unique beauty. It is a modern gem with a powerful presence, chosen by those who are drawn to its captivating and ever-changing nature.
Turquoise is steeped in ancient protective lore. While the sources do not elaborate on its metaphysical properties, its historical reputation as a guardian stone is well-known in gemological circles. It has been traditionally worn as an amulet against harm and negative forces. The sources' description of it as a "lovely shade of blue" paired with gold evokes a sense of warmth and protection, a shield of beauty. Its connection to the earth and sky reinforces its role as a grounding and balancing stone.
Collectively, these three stones offer a spectrum of meanings for the December-born: the calm wisdom of blue topaz, the transformative truth of tanzanite, and the protective strength of turquoise.
Care and Cleaning
Proper maintenance is crucial for preserving the beauty and longevity of any gemstone. The physical properties of blue topaz, tanzanite, and turquoise dictate specific care instructions.
Blue Topaz, with a standard hardness of 8 on the Mohs scale, is a relatively durable gemstone. It can withstand everyday wear but is not as hard as sapphire or diamond. The sources describe it as having "sparkling clarity," which can be maintained by regular cleaning. It is best cleaned with warm water, a mild soap, and a soft brush. Ultrasonic cleaners are generally safe for untreated blue topaz, but caution is advised for stones that may have been fracture-filled (though this is less common with topaz than with other gems). Steam cleaning should be avoided.
Tanzanite has a hardness of 6.5 to 7, making it more susceptible to scratches and abrasions than blue topaz. Its perfect cleavage in one direction also makes it vulnerable to breakage if struck with force. The sources note its captivating color, which should be preserved by gentle handling. Cleaning tanzanite jewelry requires a soft brush, mild soap, and lukewarm water. It should never be subjected to ultrasonic or steam cleaners, as the vibrations and heat can cause internal fractures. It is advisable to remove tanzanite jewelry during physical activities.
Turquoise is the softest of the three, with a hardness of 5 to 6. It is also porous and often treated with wax or oil to enhance its color and stability. The sources mention its lovely blue shades, which can be damaged by chemicals, cosmetics, and even the natural oils from the skin. To clean turquoise, simply wipe it with a soft, dry cloth. Avoid soaking it in water or using any chemicals, as this can strip the protective treatment and cause discoloration or cracking. Store turquoise jewelry separately to prevent it from being scratched by harder stones.
Conclusion
The December birthstones—blue topaz, tanzanite, and turquoise—offer a captivating trio of gems that embody the essence of winter. From the serene and wise blue topaz to the transformative and exotic tanzanite, and the ancient and protective turquoise, each stone provides a unique blend of beauty, symbolism, and historical resonance. Their varying colors, from icy blues to deep violets, not only complement the season but also allow for personal expression in jewelry design.
