In this article, we will explore the history and lore of these gemstones, delve into their geological formation and sources, examine their gemological properties, and discuss their symbolism and care requirements. We will also touch upon the modern relevance of December birthstone rings and how they continue to be a popular choice for both personal and gift purposes.
History and Lore
The December birthstones have a rich history that spans various cultures and eras. Turquoise, for example, has been used for thousands of years, with evidence of its use found in ancient Egypt, Persia, and the Americas. It was believed to offer protection, promote good travels, and bring grounded optimism. The vibrant blue-green hue of turquoise was often associated with the heavens and was considered a stone of divine wisdom.
Tanzanite, on the other hand, is a relatively modern discovery. It was first identified in the 1960s in Tanzania, from which it gets its name. Tanzanite's unique property of shifting from violet to blue under different lighting conditions made it a symbol of transformation and clarity. It quickly gained popularity and became a sought-after gemstone in the world of jewelry.
Zircon, one of the most brilliant natural gems, has been appreciated for its luminosity and sense of balance. It has been used in jewelry for centuries and is often associated with clarity and wisdom. Blue topaz, another popular December birthstone, represents calm confidence and composure. These gemstones have not only been valued for their beauty but also for their symbolic meanings, making them a perfect choice for December birthstone jewelry.
Geological Formation and Sources
The geological formation of the December birthstones is as fascinating as their history. Turquoise is a hydrated phosphate of aluminum and copper, formed in the oxidation zones of copper deposits. It is typically found in arid regions where water percolates through the ground, creating the conditions necessary for its formation. Major sources of turquoise include the American Southwest, Egypt, China, and Iran.
Tanzanite, as mentioned, is found exclusively in Tanzania, near the base of Mount Kilimanjaro. Its formation is linked to the metamorphic processes that occurred in the area millions of years ago. The unique geological conditions in Tanzania allowed for the creation of this rare gemstone, which is now a significant part of the country's gemstone industry.
Zircon, a zirconium silicate, is one of the oldest minerals on Earth. It is found in a variety of geological environments, including igneous, sedimentary, and metamorphic rocks. Zircon can be found in countries such as Australia, India, and Brazil. Its high refractive index and dispersion make it a brilliant gemstone, often compared to diamonds.
Blue topaz is a type of topaz that has been treated to enhance its blue color. Natural blue topaz is rare, and most of the blue topaz used in jewelry is created through irradiation and heat treatment. This process stabilizes the color and results in the beautiful icy blue tones that are so popular. Blue topaz is found in various parts of the world, including Brazil, the United States, and Nigeria.
Gemological Properties
The gemological properties of the December birthstones are what make them stand out in the world of jewelry. Each gemstone has its unique characteristics, which contribute to its beauty and durability.
Turquoise is known for its distinctive blue-green color, which can range from pale sky blue to deep greenish-blue. It has a hardness of 5 to 6 on the Mohs scale, making it relatively soft compared to other gemstones. Turquoise is also porous, which means it can absorb liquids and is sensitive to harsh chemicals. This porosity is why it is important to care for turquoise jewelry with special attention.
Tanzanite has a hardness of 6 to 6.5 on the Mohs scale. Its most notable feature is its trichroism, meaning it can display three different colors—violet, blue, and brown—depending on the angle of light. Tanzanite's refractive index is between 1.69 and 1.70, contributing to its brilliant sparkle. The gemstone's color is due to the presence of vanadium and is often enhanced through heat treatment.
Zircon, with a hardness of 7.5 to 8 on the Mohs scale, is a durable gemstone that can withstand daily wear. Its high refractive index (1.92 to 2.01) and dispersion (0.030 to 0.038) make it one of the most brilliant natural gems. Zircon can be found in various colors, including blue, yellow, red, and colorless, but the blue variety is particularly popular.
Blue topaz has a hardness of 8 on the Mohs scale, making it a durable gemstone suitable for everyday wear. Its refractive index is between 1.61 and 1.63, and it is known for its clarity and brilliance. The blue color of topaz is often enhanced through irradiation and heat treatment, which stabilize the color and result in the beautiful icy blue tones that are so popular.
Symbolism and Metaphysical Beliefs
The December birthstones are not only valued for their physical properties but also for their symbolic meanings and metaphysical beliefs. These gemstones have been associated with various qualities and powers across different cultures and eras.
Turquoise is often seen as a stone of protection and good fortune. It is believed to promote healing and balance, and to enhance communication and self-expression. In ancient times, it was used in rituals and ceremonies to connect with the divine and to ward off evil spirits. The stone's association with the sky and the heavens made it a symbol of divine wisdom and clarity.
Tanzanite is linked with transformation and clarity. Its ability to shift colors under different lighting conditions is seen as a metaphor for personal growth and change. It is believed to help individuals navigate transitions and to promote emotional healing and balance. Tanzanite is also associated with the heart chakra and is thought to enhance love and compassion.
Zircon is a gemstone of brilliance and balance. It is believed to enhance wisdom, clarity, and self-awareness. Zircon is also associated with the crown chakra and is thought to promote spiritual growth and connection with the higher self. The stone's high refractive index and dispersion are seen as symbols of its ability to illuminate the path forward.
Blue topaz is associated with calmness and composure. It is believed to promote inner peace, reduce stress, and enhance mental clarity. Blue topaz is also linked with the throat chakra and is thought to enhance communication and self-expression. The stone's icy blue tones are seen as a symbol of its ability to bring a sense of calm and confidence.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of December birthstone jewelry. Each gemstone has specific care requirements based on its physical properties and porosity.
Turquoise is naturally porous and sensitive to harsh chemicals and prolonged water exposure. It should be cleaned gently with a slightly damp soft cloth and dried well. Avoid using ultrasonic cleaners or steam cleaners, as these can damage the stone. It is also important to store turquoise jewelry separately from other gems to prevent scratches and to avoid sudden temperature changes.
Tanzanite requires mild care and should be stored separately from harder gems to prevent scratches. It is sensitive to high heat and should be cleaned with a soft brush and lukewarm water. Avoid exposing tanzanite to direct sunlight for extended periods, as this can cause the color to fade.
Zircon is a durable gemstone but benefits from gentle cleaning with lukewarm water, mild soap, and a soft brush. It should be stored separately from other gems to prevent scratches. Zircon is also sensitive to high heat, so it is important to avoid exposing it to extreme temperatures.
Blue topaz is easy to maintain and can be cleaned with the same approach as zircon. It is durable and can withstand daily wear, but it is still important to store it separately from other gems to prevent scratches. Blue topaz is also sensitive to high heat, so it is important to avoid exposing it to extreme temperatures.
