December is a unique month in the world of birthstones, offering not one, but four distinct gemstones to those born within its span: blue topaz, turquoise, zircon (particularly blue zircon), and tanzanite. This selection provides a diverse range of colors, histories, and symbolic meanings, making December one of the most versatile months for birthstone jewelry. The history of these assigned stones has evolved over time, with earlier traditions favoring different gems before the modern list solidified in the 20th and 21st centuries.
A Shifting Tradition
The designation of birthstones has a long and evolving history. Early birthstone lists, inspired by Biblical texts, initially associated ruby with December. However, over time, the assigned gemstones shifted. By 1870, turquoise was recognized as a December birthstone by Tiffany & Co. in their “Gregorian Birthstone Poems” pamphlet. The National Association of Jewellers (now Jewellers of America) initially listed turquoise as the primary stone in 1912, with lapis lazuli as an alternative. Zircon was added to the list in 1952 by the Jewelry Industry Council of America, and tanzanite was the most recent addition in 2002. This evolution demonstrates the dynamic nature of birthstone traditions and the influence of both historical precedent and contemporary gemstone trends.
The Allure of Blue Topaz
Blue topaz is a popular modern choice for December birthstones. While the sources do not detail specific gemological properties, it is noted for its calming energy and association with communication and emotional balance. The sources focus on its appeal as a beautiful and readily available gemstone.
Turquoise: A Stone Steeped in History
Turquoise, consistently listed as a December birthstone, holds a significant place in history and culture. It is an opaque gemstone, ranging in color from blue to green, often exhibiting veined patterns due to the remnants of the host rock. The bluer the stone, the more copper it contains, and consequently, the more valuable it is. Geologically, turquoise is a copper aluminum phosphate, formed when chemicals seep through rock in semi-humid and dry environments.
Historically, turquoise has been valued for its protective qualities and its ability to promote self-expression and compassion. It has been used in talismans and jewelry for centuries, representing a connection to ancient traditions and beliefs.
Tanzanite: A Modern Marvel
Tanzanite is a relatively recent addition to the December birthstone family, discovered in the foothills of Mount Kilimanjaro. The sources highlight its rarity and luxurious appeal, noting its velvety violet hues. While specific gemological details are not provided, its increasing popularity reflects evolving trends in the gemstone market. Tanzanite is associated with transformative symbolism.
Zircon: Brilliance and Clarity
Zircon, particularly blue zircon, is another December birthstone. The sources suggest it enhances mental clarity, intuition, and grounding. While specific details regarding its chemical composition or hardness are not provided, it is described as possessing a fiery brilliance.
Gemological Characteristics (Limited by Sources)
The provided sources offer limited gemological data. Turquoise is identified as a copper aluminum phosphate, and its color is linked to the presence of copper and iron. The sources emphasize the opaque nature of turquoise and the veined patterns often present within the stone. Blue topaz, tanzanite, and zircon are described by their color, but detailed chemical formulas, refractive indices, or hardness values are not provided.
A comparative table, based on the limited information available, is presented below:

Symbolism and Metaphysical Beliefs
Each of the December birthstones carries its own unique symbolism. Turquoise is believed to offer protection and encourage self-expression. Blue topaz is associated with calmness and emotional balance. Zircon is thought to enhance mental clarity and intuition. Tanzanite is linked to transformative symbolism. These beliefs, rooted in historical and cultural traditions, contribute to the enduring appeal of these gemstones.
Care and Cleaning
The sources do not provide specific care instructions for each gemstone. However, given the varying hardness and composition of the stones, general care guidelines are advisable. Turquoise, being relatively softer, requires gentle handling and should be protected from scratches and harsh chemicals. Topaz, zircon, and tanzanite are generally more durable but should still be cleaned with mild soap and warm water, avoiding ultrasonic cleaners or harsh abrasives.
