The provided source material is extremely limited, consisting solely of a product page for Swarovski December birthstone stud earrings from Orin Jewelers. This severely restricts the ability to create a comprehensive 2000-word article. However, based on the context of “December birthstone” and the association with Swarovski, it is reasonable to infer that the article will focus on Tanzanite, a popular alternative to Zircon for those born in December. The following article will expand upon this inference, acknowledging the limited source material and providing a detailed overview of Tanzanite based on generally accepted gemological knowledge, while explicitly stating when information extends beyond the provided source. It is important to note that the vast majority of the information presented here is not derived from the single provided source.
History and Lore
While the provided source does not offer any historical context, Tanzanite’s history is relatively recent compared to many other gemstones. Discovered in 1967 near the Mererani Hills of northern Tanzania, the gemstone quickly gained popularity after Tiffany & Co. recognized its beauty and named it after the country of origin. Prior to this naming, it was known as “bluish-violet zoisite.” Tiffany & Co.’s marketing efforts were instrumental in establishing Tanzanite as a desirable gem, positioning it as a captivating and rare alternative to sapphire.
Unlike many gemstones steeped in ancient lore, Tanzanite lacks a long tradition of mythological associations. Its discovery is modern, and its symbolism is largely based on contemporary interpretations. Some believe Tanzanite promotes spiritual awareness, intuition, and transformation. It is often associated with communication and clarity of thought. These beliefs, however, are not substantiated by the provided source and are included to provide a broader understanding of the gem’s perceived properties.
Geological Formation and Sources
The provided source offers no information regarding the geological formation or sources of Tanzanite. Tanzanite is a blue-violet variety of the mineral zoisite, a calcium aluminum silicate hydroxide. It forms within metamorphic rocks, specifically in areas where tectonic activity has created intense heat and pressure. The unique geological conditions required for its formation are exceptionally rare, making Tanzanite geographically limited to a small area – the Mererani Hills in the Manyara Region of northern Tanzania.
The gemstone is found in a relatively small mining area, approximately eight kilometers long and two kilometers wide. This limited source contributes to its rarity and value. Mining operations range from artisanal small-scale mining to more organized, larger-scale operations. The Tanzanian government closely regulates the mining of Tanzanite to ensure responsible practices and benefit the local economy.
Gemological Properties
The provided source does not detail any gemological properties. Tanzanite exhibits a range of desirable gemological characteristics. Its color is its most defining feature, displaying a vibrant blue-violet hue. This color is pleochroic, meaning it displays different colors when viewed from different angles. Typically, Tanzanite shows blue, violet, and burgundy shades. Heat treatment is commonly used to enhance the blue color and reduce the brownish tones often present in rough stones.
Here's a table summarizing key gemological properties:
| Property | Value |
|---|---|
| Chemical Formula | Ca2Al3(SiO4)3(OH) |
| Hardness (Mohs) | 6.5 - 7 |
| Specific Gravity | 6.71 - 6.81 |
| Refractive Index | 1.619 - 1.674 |
| Crystal System | Triclinic |
| Cleavage | Perfect in one direction |
| Luster | Vitreous |
Tanzanite’s hardness of 6.5 to 7 on the Mohs scale makes it relatively durable, but it requires careful handling to avoid scratches and damage. Its perfect cleavage means it can split along certain planes if subjected to a sharp blow. The refractive index contributes to its brilliance and fire.
Symbolism and Metaphysical Beliefs
The provided source does not mention any symbolism or metaphysical beliefs associated with Tanzanite. As previously mentioned, Tanzanite is often linked to spiritual awareness, intuition, and transformation in contemporary New Age practices. It is believed to facilitate communication, enhance psychic abilities, and promote a sense of calm and clarity. Some also associate it with the throat chakra, believing it aids in expressing one's truth. These interpretations are subjective and not scientifically proven.
The association with December as a birthstone is relatively recent, established as an alternative to Zircon. The choice of Tanzanite as a December birthstone reflects its beautiful color and increasing popularity. It offers a more modern and unique option for those born in December.
Care and Cleaning
The provided source does not offer any care or cleaning instructions. Due to its hardness and cleavage, Tanzanite requires careful handling. It is susceptible to damage from ultrasonic cleaners and harsh chemicals. The recommended cleaning method is to use warm, soapy water and a soft brush. Rinse thoroughly and dry with a soft cloth. Avoid exposing Tanzanite to sudden temperature changes, as this can cause fractures. It is also advisable to remove Tanzanite jewelry before engaging in strenuous activities to prevent scratches or damage. Storing Tanzanite jewelry separately from other gemstones will help prevent abrasion.
Market Value and Availability
The provided source only lists a product for sale, offering no insight into market value or availability. Tanzanite’s value is determined by its color, clarity, cut, and carat weight. The most valuable Tanzanite exhibits a deep, saturated blue-violet hue with minimal brownish tones. Clarity plays a significant role, with eye-clean stones commanding higher prices. Cut quality is crucial for maximizing brilliance and fire.
Due to its limited source and increasing demand, Tanzanite is considered a relatively rare and valuable gemstone. Prices can vary significantly depending on the quality of the stone. Larger, high-quality Tanzanite stones are particularly rare and expensive. Geologists predict that the Tanzanite deposit will eventually be depleted, further increasing its value over time.
Swarovski and Tanzanite
The provided source specifically references Swarovski Tanzanite stud earrings. Swarovski is renowned for its precision-cut crystals and high-quality jewelry. While Swarovski does not mine Tanzanite, they utilize synthetic Tanzanite-colored crystals in their jewelry designs, offering an affordable alternative to natural Tanzanite. The use of Swarovski crystals allows for wider accessibility to the color and aesthetic appeal of Tanzanite.
Conclusion
The limited information provided by the single source necessitates a broader discussion of Tanzanite, drawing upon established gemological knowledge. Tanzanite, discovered in Tanzania in 1967, has quickly become a highly sought-after gemstone, particularly as a December birthstone alternative. Its unique blue-violet color, coupled with its relative rarity, contributes to its appeal. While lacking the extensive history and lore of older gemstones, Tanzanite has garnered a reputation for promoting spiritual awareness and clarity. Proper care and handling are essential to preserve its beauty and durability. The association with Swarovski highlights the accessibility of Tanzanite-inspired designs, even beyond the reach of natural stones.
