December is unique among the months, boasting not one, but three recognized birthstones: Tanzanite, Zircon, and Turquoise. These gemstones, while differing in origin and composition, share a common thread of captivating blue hues, making them a popular choice for those born in the final month of the year. This article will delve into the history, geological origins, gemological properties, and significance of these December birthstones, offering a comprehensive overview for enthusiasts and those seeking to understand their allure.
A History Rooted in Tradition and Recent Discovery
The tradition of associating specific gemstones with birth months dates back to ancient times, though the specific stones assigned have evolved over centuries. Initially, color was the primary determinant, rather than precise gemological identification as we know it today. The modern list of birthstones solidified in the 20th century, with additions like Tanzanite reflecting more recent discoveries.
Turquoise and Zircon have longer histories of use. Turquoise, in particular, has been prized for millennia, while Zircon has been used in jewelry for centuries. Tanzanite, however, is a relatively recent addition to the world of gemstones, discovered as recently as 1967 in Tanzania. Despite its late arrival, it quickly gained popularity due to its striking color and relative rarity. The stones also hold significance as anniversary gifts, with Tanzanite marking the 24th year and Turquoise the 11th.
Geological Formation and Sources
The origins of these three birthstones are geographically diverse, reflecting their unique geological formation processes. Tanzanite, a variety of the mineral zoisite, is found almost exclusively in the Merelani Hills of northern Tanzania. Its formation requires a specific combination of calcium, silicon, aluminum, and vanadium, created through metamorphic processes. The limited geographical source contributes to its value and desirability.
Zircon, on the other hand, is found in a wider range of locations, though specific sources are not detailed in the provided materials. Turquoise forms in relatively shallow deposits, often associated with copper mines. The provided sources do not specify particular locations for Zircon or Turquoise.

Each of these December birthstones possesses distinct gemological properties that contribute to its unique appeal.
Tanzanite: This gemstone is a variety of zoisite, displaying colors ranging from blue, purple, and green, with the most sought-after color being a deep blue with a purple shimmer.
Zircon: The provided materials do not detail the gemological properties of Zircon.

Care and Cleaning
The provided sources offer limited guidance on the care and cleaning of these gemstones. However, the recommendation to rub sterling silver jewelry with a silver cloth suggests that similar gentle cleaning methods may be appropriate for other birthstone rings. Given the varying hardness and chemical compositions of Tanzanite, Zircon, and Turquoise, specific cleaning recommendations would depend on the individual stone.
