Tanzanite is a relatively recent addition to the world of gemstones, and particularly to the list of birthstones associated with December. Distinguished by its captivating range of blue and violet hues, tanzanite has rapidly gained popularity since its commercial discovery in the late 1960s. This article will explore the history, geological origins, gemological properties, and significance of this unique gemstone, drawing solely from available sources.
History and Lore
While turquoise and zircon have long-standing associations with the month of December, tanzanite is a more modern inclusion. Its story began in 1967 with the discovery of the gem in the Merelani Hills of Tanzania. The gemstone quickly attracted attention, and Tiffany & Co. played a pivotal role in its promotion and popularization. Thanks to their marketing efforts, tanzanite became one of the most sought-after gemstones in the market, and a favored choice for December birthstone jewelry.
The gemstone’s relatively recent discovery means it lacks the extensive historical lore associated with older birthstones. However, its captivating color has led to associations with tranquility, clarity of thought, and communication, particularly when set in turquoise jewelry. The color itself is often linked to positive emotional states, making it a desirable stone for those seeking a sense of peace and understanding.
Geological Formation and Sources
Tanzanite’s origin is remarkably localized. Unlike many gemstones found in multiple locations worldwide, tanzanite comes from only one place: the Merelani Hills of Tanzania. This limited geographical source contributes significantly to its rarity and value. The gemstone forms within a specific geological environment, associated with metamorphic rocks in the region.
The formation of tanzanite is a complex process involving intense heat and pressure. The resulting crystals are often pleochroic, meaning they exhibit different colors when viewed from different angles. This characteristic is particularly notable in tanzanite, displaying shades of purple, blue, and bluish-grey. Jewelers and gemologists skillfully cut and treat the stones to maximize the desirable purple and blue tones, enhancing their visual appeal.
Gemological Properties
Tanzanite exhibits a range of colors, from deep blue to light purple, and variations in between. This color variation is a key characteristic of the gemstone. It is a pleochroic stone, displaying different colors depending on the viewing angle. The most valued tanzanite stones showcase strong, vivid blue and violet hues.
While the provided sources do not detail specific hardness or chemical composition, they emphasize the gemstone’s rarity and the meticulous craftsmanship involved in its processing. The sources do not provide information on refractive index, specific gravity, or crystal system.
Symbolism and Metaphysical Beliefs
The sources primarily focus on the aesthetic appeal and market value of tanzanite, rather than detailed metaphysical properties. However, the association of turquoise, a fellow December birthstone, with tranquility and clear communication suggests a similar symbolic resonance for tanzanite. The gemstone’s captivating color and rarity contribute to its perceived value as a symbol of uniqueness and enduring beauty.
The use of tanzanite in jewelry, particularly rings, is often linked to emotional significance. The color turquoise is associated with marriage and positive relationships, suggesting that tanzanite jewelry may also be seen as a symbol of love and commitment.
Care and Cleaning
The provided sources do not offer specific guidance on the care and cleaning of tanzanite. However, given its relative rarity and value, it is reasonable to assume that tanzanite jewelry requires careful handling and maintenance. Further research beyond the provided sources would be necessary to provide detailed care instructions.
Tanzanite and Forever Roses
Interestingly, one source highlights the use of tanzanite as inspiration for a unique product: the Tanzanite Forever Rose. This item features a real rose dipped in 24K gold, with a lacquer finish designed to capture the beautiful blue/purple coloration of tanzanite. The popularity of these birthstone roses indicates a growing appreciation for the gemstone and its aesthetic qualities. The Forever Rose is a testament to the enduring appeal of both the natural beauty of a rose and the captivating allure of tanzanite.
The Limited Supply of Tanzanite
A significant point emphasized by the sources is the limited supply of tanzanite. Estimates suggest that the gemstone’s supply may be exhausted within the next few decades. This scarcity further enhances its value and desirability, making it a prized possession for collectors and jewelry enthusiasts. The limited geographical source – the Merelani Hills of Tanzania – contributes directly to this impending scarcity.
December Birthstone Options
The sources indicate that December has four birthstones: turquoise, tanzanite, blue topaz, and blue zircon. This provides individuals born in December with a variety of options when selecting birthstone jewelry. The choice often depends on personal preference and the desired aesthetic. The availability of tanzanite may also influence the decision, with some sources suggesting Sapphire Sparkle Forever Roses as a substitute when tanzanite is unavailable.
Vintage and Modern Tanzanite Jewelry
The sources highlight the availability of tanzanite jewelry in both vintage and modern styles. Vintage tanzanite jewelry, particularly pieces from the mid-20th century, often showcases unique designs and craftsmanship. Modern tanzanite jewelry offers a wider range of styles and settings, catering to contemporary tastes. The availability of tanzanite in both vintage and modern jewelry makes it accessible to a broad audience.
Conclusion
Tanzanite is a captivating and relatively recent addition to the world of birthstones. Its unique geological origin, stunning color range, and increasing rarity have contributed to its growing popularity. While lacking the extensive historical lore of older gemstones, tanzanite has quickly established itself as a prized possession for jewelry enthusiasts and a meaningful symbol for those born in December. Its limited supply and captivating beauty ensure that tanzanite will continue to be a sought-after gemstone for years to come.
