December boasts a unique distinction among the months: it has not one, but three recognized birthstones – Turquoise, Tanzanite, and Blue Zircon. While Blue Topaz is frequently marketed as a December birthstone, the sources primarily highlight these three gems as the traditional and modern choices for those born in the final month of the year. Each stone carries its own history, symbolism, and gemological properties, offering a diverse range of options for jewelry and personal adornment. This article will delve into the characteristics of each of these December birthstones, exploring their origins, meanings, and care.
History and Lore
Turquoise is the most historically recognized of the December birthstones. Sources indicate its long-standing association with December birthdays, establishing it as a “commonly known” choice. While a detailed historical account is limited within the provided materials, the emphasis on its “stunning color and versatile wearability” suggests a consistent presence in jewelry collections.
Tanzanite, a more recent addition to the birthstone list, was officially recognized in 1952. Its “deep blue tones” quickly established it as a desirable gem, and its inclusion as a December birthstone reflects its growing popularity.
Blue Zircon, though less common in contemporary jewelry, also holds a place as a December birthstone. The sources note that while not as frequently seen in recent years, it remains a “bold and beautiful option” for those celebrating a December birthday.
Geological Formation and Sources
The provided sources do not detail the geological formation processes of these gemstones, nor do they specify particular mining locations beyond a general mention of availability. However, the materials do indicate that Turquoise, Tanzanite, and Blue Zircon are all distinct gemstones with unique origins. The emphasis on “vintage, pre-loved and modern” jewelry featuring these stones suggests a history of mining and trade, though specific source countries are not provided.
Gemological Properties
The sources offer varying levels of detail regarding the gemological properties of each birthstone.
Turquoise: The materials highlight its “stunning color” and “versatile wearability,” but do not provide specific details regarding its chemical composition, hardness, or clarity. It is mentioned in the context of beaded bracelets and pocket knives, suggesting a degree of durability suitable for these applications.
Tanzanite: This December birthstone is described as having “deep blue tones.” The sources note that most Tanzanite begins as brownish zoisite and undergoes heat treatment to achieve its characteristic blue to violet hues. Importantly, this heat treatment is considered permanent, with “no additional durability concerns” resulting from the process. Tanzanite is rated at 6 to 7 on the Mohs scale of hardness, making it susceptible to scratching and abrasion. It is recommended for settings in earrings or pendants, and while it can be worn in rings, a protective mounting and careful handling are advised. It is vulnerable to cracking with extreme temperature changes and is attacked by hydrochloric and hydrofluoric acids.
Blue Zircon: The sources characterize Blue Zircon as “bold and beautiful,” but provide no specific gemological data.
The following table summarizes the limited gemological information available from the sources:
| Gemstone | Color | Hardness (Mohs) | Treatment | Recommended Setting |
|---|---|---|---|---|
| Tanzanite | Blue to Violet | 6-7 | Heat Treatment | Earrings, Pendants |
| Turquoise | Stunning Color | Not Specified | Not Specified | Bracelets, Pocket Knives |
| Blue Zircon | Bold & Beautiful | Not Specified | Not Specified | Not Specified |
Symbolism and Metaphysical Beliefs
The sources touch upon the symbolism associated with these birthstones, though the depth of information varies. Blue Topaz, though not a primary focus, is “associated with loyalty and love.” Turquoise is presented as a gemstone that embodies a “calm body of water,” representing tranquility and relaxation. The marketing materials for a specific ring design emphasize the symbolism of the stone’s shape, referencing the “birth canal” and “fruitful life.”
The sources do not provide extensive details regarding the historical or cultural metaphysical beliefs surrounding Turquoise, Tanzanite, or Blue Zircon.
Care and Cleaning
The provided materials offer specific care instructions primarily for Tanzanite. It is recommended to clean Tanzanite with warm, soapy water. Ultrasonic and steam cleaners are explicitly not recommended due to the stone’s sensitivity to heat and potential for damage. The sources suggest that Tanzanite is best suited for earrings and pendants due to its relative fragility, but can be worn in rings with appropriate protection.
No specific cleaning or care instructions are provided for Turquoise or Blue Zircon.
December Birthstone Jewelry: Styles and Options

The materials also suggest that December birthstone jewelry is available for both men and women, with options ranging from classic bracelets to functional accessories like turquoise pocket knives.
