December's birthstone tradition is rich with color and meaning, symbolized by two stunning gemstones: tanzanite and blue topaz. These stones are celebrated for their vibrant hues and enduring beauty, making them popular choices for jewelry, especially in the form of earrings. December birthstone earrings in gold, whether in yellow, white, or rose gold, serve as both elegant adornments and meaningful gifts, capturing the essence of the month through their gemological properties and cultural significance. This article delves into the history, properties, and symbolism of tanzanite and blue topaz, the materials and craftsmanship involved in gold jewelry, and the broader cultural and commercial significance of December birthstone earrings.
History and Lore
December birthstone jewelry has a long and storied history, rooted in ancient traditions and evolving into a modern symbol of celebration and personal identity. The tradition of associating specific gemstones with months of the year dates back centuries, with records of such associations found in ancient texts from as early as 3000 BCE. These texts often linked gemstones with specific attributes, such as protection, health, or prosperity, making them valuable talismans and symbols.
Tanzanite, a relatively modern discovery, was first identified in the 1960s in Tanzania, from which it derives its name. This gemstone quickly gained popularity due to its striking blue and purple hues, which are attributed to trace amounts of vanadium. Tanzanite’s discovery marked a significant moment in gemology, as it was the first new gemstone to be introduced in the 20th century. Its vibrant color and unique properties made it an instant favorite, and it was soon adopted as the December birthstone in the 1970s.
Blue topaz, on the other hand, has a much older history, with its use in jewelry dating back to ancient civilizations. Known for its clear blue color, blue topaz has been valued for its beauty and durability. In some cultures, it was believed to have calming properties and was used to ward off negative energies. The use of blue topaz in December birthstone jewelry highlights its enduring appeal and its role in both historical and contemporary jewelry traditions.
Geological Formation and Sources
The geological formation of tanzanite and blue topaz is a fascinating process that reflects the Earth's dynamic nature. Tanzanite is a variety of the mineral zoisite and is found only in the Merelani Hills of Tanzania. This limited geographical distribution makes tanzanite a rare and valuable gemstone. The transformation of zoisite into tanzanite occurs under specific geological conditions, including high heat and pressure, and the presence of trace elements such as vanadium. The unique coloration of tanzanite is the result of a process called irradiation, which alters the crystal structure of the gemstone, creating its characteristic blue and purple hues.
Blue topaz, in contrast, is more widely distributed and can be found in various parts of the world, including Brazil, Mexico, the United States, and Japan. It forms in igneous rocks, particularly in rhyolite and granite, and is often found in veins and cavities. The blue color of blue topaz is due to the presence of trace amounts of iron and the effects of natural irradiation. This gemstone is known for its clarity and brilliance, making it a popular choice for jewelry.
The sources of these gemstones play a crucial role in the jewelry industry. Tanzanite's limited availability has made it a highly sought-after gemstone, with Tanzania being the sole source. This exclusivity contributes to its value and desirability. Blue topaz, while more abundant, is still prized for its beauty and affordability, making it accessible to a wider audience. The availability of these gemstones in gold jewelry allows for a diverse range of designs, from classic to contemporary, catering to different tastes and preferences.
Gemological Properties
Understanding the gemological properties of tanzanite and blue topaz is essential for appreciating their use in December birthstone jewelry. Tanzanite has a hardness of 6 to 6.5 on the Mohs scale, which means it is relatively soft compared to other gemstones. This lower hardness requires careful handling and setting to prevent scratches and damage. Tanzanite is also pleochroic, meaning it exhibits different colors when viewed from different angles. This property adds to its visual appeal, as the gemstone can display shades of blue, purple, and brown depending on the light and viewing angle.
Blue topaz, on the other hand, has a higher hardness of 8 on the Mohs scale, making it more durable and suitable for everyday wear. Its refractive index is approximately 1.62, which contributes to its brilliance and clarity. Blue topaz is also known for its low dispersion, which means it does not display the same level of fire as diamonds or other high-dispersion gemstones. However, its clear blue color and high transparency make it a popular choice for jewelry, especially in gold settings where its color can be enhanced.
The use of gold in December birthstone earrings adds another layer of gemological consideration. Gold is a soft metal, with a hardness of 2.5 to 3 on the Mohs scale, which means it requires alloying with other metals to increase its durability. In jewelry, gold is often mixed with metals such as silver, copper, and zinc to create different karats, such as 14k or 18k gold. These alloys provide the necessary strength to hold gemstones securely while maintaining the beauty and luster of the metal. The choice of gold color, whether yellow, white, or rose gold, also affects the overall appearance of the jewelry, with each hue complementing the color of the gemstone in unique ways.
Symbolism and Metaphysical Beliefs
The symbolism and metaphysical beliefs associated with tanzanite and blue topaz add depth to their significance as December birthstones. Tanzanite is often linked with emotional healing and spiritual transformation. Its vibrant colors are believed to promote inner peace and balance, making it a popular choice for those seeking emotional stability and personal growth. In some cultures, tanzanite is also associated with creativity and intuition, encouraging the wearer to explore their inner self and connect with their higher purpose.
Blue topaz, on the other hand, is associated with calmness, clarity, and wisdom. It is believed to have a soothing effect on the mind and emotions, helping to reduce stress and anxiety. In ancient times, blue topaz was used as a protective stone, believed to ward off negative energies and bring good fortune. The clear blue color of blue topaz is also associated with truth and honesty, making it a symbol of integrity and trustworthiness.
The combination of tanzanite and blue topaz in December birthstone jewelry reflects the dual nature of the month, symbolizing both the transformative energy of tanzanite and the calming presence of blue topaz. This duality is particularly fitting for December, a month of reflection, celebration, and new beginnings. The use of gold in these pieces further enhances their symbolism, as gold has long been associated with wealth, purity, and eternal value.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of December birthstone earrings in gold. Given the relative softness of tanzanite and the potential for scratches, it is important to handle these gemstones with care. Tanzanite should be protected from harsh chemicals and abrasive materials, as these can dull its surface and affect its color. It is advisable to store tanzanite jewelry separately from other gemstones to prevent scratches and damage.
Blue topaz, being a harder gemstone, is more resistant to scratches and can be cleaned with mild soap and warm water. However, it is still important to avoid exposure to harsh chemicals and extreme temperatures, as these can affect its clarity and color. Gold jewelry, whether yellow, white, or rose gold, should be cleaned with a soft cloth and a mild detergent to maintain its luster and prevent tarnishing. It is also important to avoid using ultrasonic cleaners for gold jewelry, as the vibrations can loosen gemstones and damage the metal.
When caring for December birthstone earrings, it is important to consider the type of setting and the materials used. Earrings with screw backs and threaded posts should be handled carefully to avoid damaging the mechanism. It is also advisable to remove jewelry before engaging in activities that may expose it to physical stress or chemicals, such as swimming, exercising, or using household cleaners.
