This article will explore the origins, properties, and cultural relevance of each of these stones, providing a comprehensive overview of their role as birthstones for those born on December 22nd.
December is a month of transition, marking the end of the year and often associated with the cool tones of winter. The selection of these three gemstones reflects this essence, evoking feelings of serenity, spiritual depth, and transformation. The multiplicity of birthstones for December allows for a wider selection based on personal preference, price point, and individual resonance.
History and Lore
The association of gemstones with specific months and days dates back centuries, with roots in ancient astrological beliefs and traditions. Turquoise boasts the longest history of the three, having been revered by civilizations such as the Egyptians, Persians, and Native Americans for its protective qualities and association with good fortune. Its use in jewelry and ornamentation extends back millennia.
Zircon, while known since antiquity, was often mistaken for other gemstones due to its brilliance. It enjoyed widespread popularity in jewelry during the early 20th century, solidifying its place as a traditional December birthstone.
Tanzanite is the most recent addition to the birthstone family, discovered in the foothills of Mount Kilimanjaro in Tanzania. Despite its relatively recent discovery, it quickly gained prominence due to its striking color and rarity, becoming a symbol of transformation and success. The inclusion of all three stones for December 22nd acknowledges both long-standing traditions and the emergence of new, captivating gemstones.
Geological Formation and Sources
Each of these birthstones originates through distinct geological processes and is sourced from specific locations around the globe. Turquoise forms in relatively shallow subsurface environments during the weathering and alteration of aluminum-rich volcanic rocks. Significant sources include the southwestern United States, Iran, and China.
Zircon is one of the oldest minerals on Earth, forming in igneous rocks and metamorphic environments. It is found in various locations, including Sri Lanka, Cambodia, and Australia. The blue varieties of zircon are particularly prized.
Tanzanite’s origin is remarkably localized. It is found in a small area near the Merelani Hills of northern Tanzania, at the base of Mount Kilimanjaro. This limited geographical source contributes significantly to its rarity and value. The geological conditions necessary for its formation are unique to this region, making Tanzanite a truly exceptional gemstone.
Gemological Properties
Each gemstone possesses unique gemological properties that contribute to its distinct appearance and value.
Tanzanite: This gemstone is known for its trichroism, displaying different colors – blue, violet, and burgundy – depending on the viewing angle. This characteristic adds to its allure and complexity.
Turquoise: Characterized by its opaque nature and vibrant blue-green color, turquoise is a hydrated phosphate of copper and aluminum. Its color is influenced by the presence of copper and iron.
Zircon: Zircon exhibits a high refractive index, contributing to its brilliance and fire. Blue zircon is often created through heat treatment of naturally occurring brown zircon.

Symbolism and Metaphysical Beliefs
Throughout history, these gemstones have been attributed with various symbolic meanings and metaphysical properties. Turquoise has long been considered a protective stone, believed to ward off negative energy and bring good fortune. It is often associated with healing and spiritual grounding.
Zircon, particularly blue zircon, is believed to promote wisdom, honor, and prosperity. Its association with ancient traditions lends it an air of mystique and power.
Tanzanite is often linked to spiritual exploration and awakening. Its deep blue tones are said to stimulate the throat and third eye chakras, fostering communication and enhancing intuition. It is also believed to symbolize transformation, making it an ideal talisman for those undergoing significant life changes. The stone’s association with personal growth and evolution resonates with the idea that individuals born on December 22nd are destined for a journey of self-discovery.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of these gemstones. Tanzanite, with a hardness of 6.5 to 7 on the Mohs scale, is relatively soft and susceptible to scratches. It should be stored separately from harder gemstones and cleaned with warm, soapy water and a soft cloth. Avoid ultrasonic cleaners and harsh chemicals.
Turquoise, being a softer stone (5-6 on the Mohs scale), requires gentle handling. Avoid abrasive cleaners and prolonged exposure to sunlight or extreme temperatures. Cleaning should be done with a soft cloth and mild soapy water.
Blue zircon, with a hardness of 6.5 to 7.5, is more durable than tanzanite and turquoise but still requires careful handling. It can be cleaned with warm, soapy water and a soft brush. Avoid harsh chemicals and ultrasonic cleaners.
Conclusion
The December 22nd birthstones – tanzanite, turquoise, and blue zircon – represent a captivating blend of history, symbolism, and aesthetic allure. From the ancient protective qualities of turquoise to the modern elegance of tanzanite and the enduring brilliance of zircon, each gemstone offers a unique connection to the month of December and the individuals born under its influence.
