December is unique among the months, boasting not one, but two recognized birthstones: blue topaz and tanzanite. Both gemstones offer captivating beauty and distinct characteristics, making them cherished choices for jewelry and symbolic gifts. This article will delve into the history, geological origins, gemological properties, and significance of these December birthstones, drawing exclusively from available sources.
History and Lore
The association of specific gemstones with months of the year has evolved over time. While modern birthstone lists are relatively standardized, historical variations existed. Blue topaz, as a December birthstone, is linked to traditions of gifting gemstones to symbolize affection and love. The sources highlight its calming and soothing properties, suggesting a long-held belief in its emotional benefits.
Tanzanite, a more recent addition to the birthstone canon, carries a unique history tied to its singular origin. Discovered in Tanzania, near Mount Kilimanjaro, the gemstone is named after the country itself, a testament to its exclusivity. Its relatively recent introduction means its lore is still developing, but its rarity immediately established it as a precious and desirable gem. The sources indicate that tanzanite is a dynamic December birthstone, being the oldest mineral on Earth, giving insight into how the planet was formed.
Geological Formation and Sources
Blue topaz is not discussed in detail regarding its geological formation within the provided sources. However, the sources do mention tanzanite’s specific and limited origin. Tanzanite is found in a small area near Mount Kilimanjaro in Tanzania, making it a remarkably rare gemstone. It belongs to the mineral zoisite and exhibits a range of exquisite blue-purple colors.
Zircon, another December birthstone mentioned, is frequently mined in Australia, but also found in Thailand, Sri Lanka, Tanzania, Cambodia, Canada, and the United States. The sources note that most tanzanite undergoes heat treatment to enhance its blue shades, similar to sapphire, and minimize natural brown tones. This treatment is a common practice in the industry to maximize the gem’s appeal.
Gemological Properties
The provided sources offer some insight into the gemological properties of blue topaz and tanzanite. Blue topaz, featured in sterling silver settings with simulated diamonds, is described as a brilliant gemstone. It is presented as a round cut gemstone. The sources specify that the earrings are made from 925 sterling silver.
Tanzanite is noted for its variety of blue-purple colors. The sources indicate that tanzanite can be prone to scratching, suggesting a relative fragility compared to harder gemstones, and is therefore best suited for earrings and pendants.
The sources also mention zircon, noting its deep blue color and unique way it catches the light.
A table summarizing the available gemological information is presented below:
| Gemstone | Color(s) | Setting/Metal | Treatment | Durability |
|---|---|---|---|---|
| Blue Topaz | Blue | Sterling Silver | Not Specified | Not Specified |
| Tanzanite | Blue-Purple | 14K Yellow Gold | Heat Treated | Prone to Scratching |
| Zircon | Deep Blue | Not Specified | Not Specified | Not Specified |
Symbolism and Metaphysical Beliefs
Blue topaz is associated with love and affection, embodying calming and soothing properties. This suggests a symbolic connection to emotional well-being and peaceful relationships.
Tanzanite is linked to the heart, intellect, intuition, and purity. The sources also connect turquoise – another December birthstone – with loyalty, great love, health, good fortune, and peace. Zircon is associated with chastity, virtuousness, and trustworthiness. These attributions highlight the diverse range of meanings associated with December birthstones, offering a wealth of symbolic choices for gift-giving.
Care and Cleaning
The sources provide specific care instructions for jewelry containing pearls and gemstones. For gemstones, the recommendation is to clean them with warm water and mild soap, avoiding contact with perfume, hairspray, and other chemicals. They should be stored separately from other jewelry to prevent scratches.
Specifically for gold jewelry with pearls or gemstones, the sources emphasize careful handling. Pearls, being delicate natural products, require gentle cleaning with a soft, damp cloth and should be stored separately from sharp materials. The sources also state that all gold jewelry is made of real 14 carat gold, also indicated with a grade of 585.
Conclusion
December’s birthstones, blue topaz and tanzanite, represent a captivating blend of tradition and rarity. Blue topaz offers a classic beauty and symbolic connection to love and tranquility, while tanzanite embodies exclusivity and a vibrant range of colors. Both gemstones, along with zircon and turquoise, provide meaningful options for those seeking a December birthstone gift or a piece of jewelry with personal significance.
