December is a month rich in tradition and celebrated with a variety of gemstones. While multiple gems are associated with this winter month, individuals born on December 11th have a particularly special connection to tanzanite and turquoise, two stones steeped in history, lore, and captivating beauty. This article explores the origins, properties, symbolism, and significance of these December birthstones, drawing upon available knowledge to provide a comprehensive overview for enthusiasts and those seeking to understand the unique allure of these gems.
History and Lore
Turquoise boasts an exceptionally long history, recognized as one of the world’s oldest gemstones. Evidence suggests its use dates back as far as 7000 BCE, with discoveries in burial sites in western Iran. Ancient civilizations across the globe prized this stone, including the Egyptians, who considered it a holy stone bringing good luck, fertility, and even improving a warrior’s accuracy. It was associated with the goddess Hathor and fashioned into amulets and beads. Ancient Chinese carvers also utilized turquoise over 3,000 years ago. Native American tribes in the southwestern United States held turquoise in high regard, using it in ceremonies, as a medium of exchange, and in jewelry and amulets. The Apache believed following a rainbow would lead to turquoise, and attaching it to weaponry would improve aim. Pueblo and Hopi tribes attributed its color to the sky and the movements of lizards, respectively. The name “turquoise” itself originates from the French expression “pierre tourques,” meaning “Turkish stone,” reflecting its likely arrival in Europe through Turkish trade routes in the 13th century.
Tanzanite, in contrast, is a relatively recent discovery. It was unearthed in the foothills of Mount Kilimanjaro in Tanzania, and quickly gained prominence in the jewelry world. Its association with the zodiac sign Sagittarius, representing those born between November 22nd and December 21st, imbues it with a symbolic connection to adventurous spirits and optimistic outlooks. While not as ancient in its lore as turquoise, tanzanite has rapidly acquired metaphysical significance, believed to bring intuition and vitality.
Geological Formation and Sources
Turquoise is a semi-translucent to opaque gem, typically found in shades of blue to green, often exhibiting veins of matrix. Significant deposits are located in the southwestern United States, particularly in Arizona and California, as well as in Iran, China, and Mexico. It forms through a chemical sedimentary process, typically in arid regions where copper-rich groundwater interacts with phosphate-rich rocks.
Tanzanite, on the other hand, is found in a very limited geographical area: the Merelani Hills of northern Tanzania. This singular origin contributes to its rarity and value. It is a trichroic gemstone, meaning it displays three different colors – blue, violet, and burgundy – depending on the viewing angle.
Gemological Properties
Turquoise’s color ranges from blue to green, and its appearance can vary due to the presence of matrix. It has a Mohs hardness rating of 5 to 6, making it relatively soft and susceptible to scratching.
Tanzanite is known for its deep blues and violet tones, with the blue variety being considered the most valuable. Sources describe it as having a “velvety” appearance due to its saturated color. While specific gemological data like refractive index and chemical composition are not provided in the available sources, it is noted as a coveted gemstone.

Symbolism and Metaphysical Beliefs
Throughout history, turquoise has been attributed with numerous beneficial powers, including guaranteeing health and good fortune. It was believed to protect wearers from falls, particularly from horses, and would even break into pieces to warn of impending disaster. Hindu mystics believed viewing turquoise after a new moon would bring wealth.
Tanzanite is believed to enhance intuition and vitality. Its connection to Sagittarius is thought to resonate with those possessing an adventurous spirit and optimistic outlook. It is also considered a traditional gift for the twenty-fourth wedding anniversary.
Care and Cleaning
Due to its relatively low hardness, turquoise requires careful handling. It is susceptible to scratching and damage from harsh chemicals. Cleaning should be done gently with a soft cloth and mild soap and water. Avoid ultrasonic cleaners and harsh cleaning agents.
Specific care instructions for tanzanite are not detailed in the provided sources, but its value and potential sensitivity suggest similar gentle cleaning practices are advisable.
December’s Unique Gemstone Combination
The association of both tanzanite and turquoise with December, and specifically December 11th, creates a unique and compelling gemstone pairing. The ancient history and protective symbolism of turquoise complement the modern allure and metaphysical properties of tanzanite. This combination reflects the diverse and captivating nature of December’s birthstone legacy. The sources suggest that the connection between the December 11th birthstone and the December 7th birthstone color, turquoise, further enriches the narrative of December’s gems.
Conclusion
Turquoise and tanzanite represent a fascinating duality within the realm of December birthstones. Turquoise, with its millennia-long history and cultural significance, embodies tradition and protection. Tanzanite, a more recent discovery, offers a modern elegance and a connection to intuition and vitality. Together, they encapsulate the spirit of December, offering wearers a beautiful and meaningful connection to their birth month. These gems continue to captivate and inspire, serving as enduring symbols of beauty, history, and personal significance.
