December boasts a unique distinction among the birthstones – not one, but three gemstones represent the month: blue topaz, tanzanite, and turquoise. These stones, each with its own history, properties, and symbolism, offer a diverse range of options for those seeking a meaningful birthstone ring. This article will delve into the characteristics of each gem, their historical context, and their presence in contemporary jewelry, particularly heart-shaped rings and other designs.
History and Lore
The association of gemstones with specific months dates back to ancient times, though the specific assignments have evolved. While zircon was historically linked to December, the modern selection includes the more recently discovered tanzanite alongside the long-appreciated topaz and turquoise. Turquoise, one of the oldest gemstones used in jewelry, symbolizes protection and good fortune, with a history stretching back millennia. Topaz has been valued for centuries, representing wealth and royalty. Tanzanite, discovered relatively recently, quickly gained popularity for its striking violet-blue hues and association with spiritual growth and transformation.
The December birthstones are often linked to the imagery of the winter season – the cool blues evoking snowy landscapes and clear winter skies. This connection is particularly noted in the symbolism of turquoise, topaz, and zircon, which are said to represent the December weather. The significance of a December birthstone extends beyond mere aesthetics; it is believed to imbue the wearer with qualities like wisdom, serenity, and good fortune.
Geological Formation and Sources
The sources and formation of these three gemstones differ significantly. Blue topaz, a variety of the silicate mineral topaz, is found in various locations globally. Its Mohs hardness of 8/10 makes it a durable choice for everyday wear, even in engagement rings. Turquoise is an opaque, blue-to-green mineral, a hydrated phosphate of copper and aluminum, formed in arid regions through a secondary enrichment process.
Tanzanite, however, is exceptionally rare, found in only one location: the Merelani Hills of northern Tanzania. This limited source contributes to its value and mystique. The geological conditions necessary for its formation are unique to this region, making it a truly exclusive gemstone.
Gemological Properties
Each December birthstone possesses distinct gemological properties.
Blue Topaz: Typically displays a vibrant blue color, though it can also be found colorless, pink, yellow, or peach. Its hardness of 8 on the Mohs scale makes it relatively resistant to scratching.
Tanzanite: Exhibits a pleochroic effect, meaning it displays different colors depending on the viewing angle – typically blue, violet, and burgundy. Its hardness is between 6 and 7 on the Mohs scale, requiring more careful handling than topaz.
Turquoise: Is characterized by its opaque nature and varying shades of blue and green, often with matrix patterns (veins of other minerals). Its hardness ranges from 5 to 6 on the Mohs scale, making it softer and more susceptible to damage than topaz or tanzanite.
The following table summarizes key properties:
| Gemstone | Chemical Formula | Hardness (Mohs) | Color(s) | Transparency |
|---|---|---|---|---|
| Blue Topaz | Al₂SiO₄(OH,F)₂ | 8 | Blue, colorless, pink, etc. | Transparent |
| Tanzanite | Ca₂Al₃(SiO₄)₃(OH) | 6-7 | Blue, violet, burgundy | Transparent |
| Turquoise | CuAl₆(PO₄)₄(OH)₈·4H₂O | 5-6 | Blue, green | Opaque |
Symbolism and Metaphysical Beliefs
Throughout history, each of these gemstones has been attributed with specific meanings and powers. Blue topaz is believed to represent communication, wisdom, and serenity. It is often associated with promoting honesty and self-control. Tanzanite is linked to spiritual growth, transformation, and intuition. It is thought to facilitate communication with the higher self and enhance psychic abilities. Turquoise has long been considered a protective stone, symbolizing good fortune and warding off negative energy. It is also associated with friendship and loyalty.
These symbolic associations contribute to the popularity of December birthstone rings as meaningful gifts, representing not only affection but also wishes for the recipient’s well-being and happiness.
December Birthstone Rings: Styles and Designs
December birthstone rings are available in a wide array of styles, catering to diverse tastes and preferences. Classic solitaire rings featuring a single blue topaz, tanzanite, or turquoise are popular choices. Halo and three-stone designs, incorporating smaller diamonds or other gemstones, add extra sparkle and sophistication. Boho-inspired rings showcase turquoise in more organic settings, often with silverwork and intricate details. Minimalist stackable bands offer a contemporary look, allowing for personalized combinations.
Specific designs, such as heart-shaped rings, are particularly significant. A heart-shaped ring featuring a blue topaz cubic zirconia, set in sterling silver with white CZ accents, embodies the themes of love, loyalty, and friendship. Platinum plated sterling silver rings with blue topaz gemstones are also available, offering a durable and radiant finish. The Karat Store offers classic blue topaz solitaires, tanzanite halo designs, and turquoise statement rings.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of December birthstone rings. Topaz, with its higher hardness, is relatively durable and can be cleaned with warm soapy water and a soft brush. Tanzanite, being softer, requires more gentle handling. Avoid harsh chemicals and ultrasonic cleaners, as they can damage the stone. Turquoise is porous and sensitive to chemicals, so it should be cleaned with a soft, damp cloth and mild soap. Avoid prolonged exposure to sunlight and humidity, as this can affect its color.
Rings with platinum plating, like those from Saslow Shenebrys, require special attention as they cannot be resized through traditional methods. These rings are custom-ordered to ensure a perfect fit and maintain the integrity of the plating.
Conclusion
The December birthstones – blue topaz, tanzanite, and turquoise – offer a captivating blend of beauty, history, and symbolism. Each gemstone possesses unique properties and appeals to different aesthetic preferences. Whether seeking a classic solitaire, a modern halo design, or a bohemian statement piece, a December birthstone ring provides a meaningful and elegant expression of personal style and connection to the month of December. The availability of these stones in various cuts, settings, and metals ensures a perfect match for every individual, making them cherished heirlooms for generations to come.
