How Long Will Tanzanite Last? Exploring the Enduring Beauty and Durability of This Unique Gemstone
Tanzanite, a gem celebrated for its mesmerizing violet-blue hues, has captivated jewelry enthusiasts for decades. But a common question among those considering this precious stone is: how long will tanzanite last? The answer, like the gem itself, is multifaceted. In essence, tanzanite can last for generations with proper care, but understanding its specific durability is crucial.
Understanding Tanzanite's Durability: The Mohs Hardness Scale
When we talk about how long a gemstone will "last," we're often referring to its ability to withstand wear and tear. This is best understood by looking at its hardness, typically measured on the Mohs scale. The Mohs scale ranks minerals from 1 (talc) to 10 (diamond) based on their scratch resistance.
- Tanzanite ranks at a **6.5 to 7 on the Mohs scale**.
This means that while tanzanite is harder than many common materials, it is softer than some other popular gemstones. For comparison:
- Diamonds are a 10 on the Mohs scale.
- Rubies and Sapphires are a 9.
- Emeralds are a 7.5 to 8.
- Quartz (which includes amethyst and citrine) is a 7.
What does this Mohs hardness translate to in terms of longevity? It means tanzanite is susceptible to scratches from harder materials and can chip or fracture if subjected to strong impacts. Therefore, its lifespan in a piece of jewelry is heavily dependent on the wearer's lifestyle and the gemstone's setting.
Factors Affecting Tanzanite's Longevity
Beyond its inherent hardness, several factors influence how long your tanzanite will remain beautiful and intact:
1. Wearer's Lifestyle and Activity Level:
This is perhaps the most significant factor. If your tanzanite jewelry is worn daily, especially in activities that involve a risk of impact or abrasion (like gardening, sports, or strenuous household chores), it is more likely to sustain damage over time. For those with a more active lifestyle, it is advisable to reserve tanzanite pieces for special occasions or ensure they are set in protective mountings.
2. Setting of the Gemstone:
The way a tanzanite is set in jewelry plays a crucial role in its protection. Gemstones with protective settings are less prone to damage.
- Bezel Settings: These settings wrap a thin band of metal around the entire perimeter of the gemstone, offering excellent protection against chips and abrasions.
- Prong Settings: While popular for showcasing a gem's brilliance, standard prong settings leave the tanzanite more exposed. However, a well-designed prong setting with lower-profile prongs can still offer reasonable protection.
- Recessed Settings: Settings where the gemstone sits lower within the metal, offering some protection from direct impact.
For rings, which are particularly susceptible to knocks and bumps, considering a bezel setting or a design that minimizes the gemstone's exposure is highly recommended for long-term wear.
3. Jewelry Type:
Different types of jewelry experience varying levels of wear:
- Rings: The most exposed to daily wear and tear.
- Pendants and Earrings: Generally experience less impact than rings, making them more durable for everyday wear.
- Bracelets: Can be subject to frequent bumps and scrapes depending on the wearer's activities.
4. Cleaning and Maintenance:
Regular and proper cleaning is essential for maintaining tanzanite's beauty and can indirectly contribute to its longevity by preventing the buildup of abrasive dirt and grime. However, the cleaning method is critical.
- Avoid: Ultrasonic cleaners and steam cleaners can be detrimental to tanzanite, as they can cause fractures or discoloration due to heat and vibrations. Harsh chemicals and abrasive cleaning agents should also be avoided.
- Recommended: A soft brush, mild soap (like dish soap), and warm water are the safest methods for cleaning tanzanite. Gently scrub the gemstone and its setting, then rinse thoroughly and dry with a soft, lint-free cloth.
5. Exposure to Extreme Temperatures and Chemicals:
Tanzanite is known to be sensitive to rapid temperature changes. Extreme heat can potentially cause damage or alter the stone's color. Likewise, exposure to household chemicals, perfumes, hairsprays, and even lotions can dull its luster over time and may even affect the stone's integrity if left on the surface.
"Tanzanite's unique trichroism, the ability to display three different colors when viewed from different angles, is a result of its crystalline structure. This structure, while beautiful, also makes it slightly more susceptible to cleavage planes, meaning it can be split if struck sharply along these planes."
The Lifespan of Tanzanite: A Generational Gemstone
So, to directly answer the question: how long will tanzanite last?
When treated with respect and appropriate care, tanzanite is a gemstone that can absolutely last for generations. Heirloom quality tanzanite jewelry has been passed down and will continue to be cherished for centuries. It is not a fragile stone in the sense that it will disintegrate, but rather it requires a mindful approach to wear and maintenance.
Think of it this way: a diamond will last indefinitely with minimal care due to its extreme hardness. A tanzanite, with its Mohs hardness of 6.5-7, requires more attention. However, for an average wearer who removes jewelry during strenuous activities, cleans it gently, and stores it properly, a tanzanite engagement ring, for instance, can easily endure for 50, 100, or even more years, retaining its captivating beauty.
Tips for Ensuring Your Tanzanite Lasts:
- Remove jewelry before engaging in physical activities, housework, or before applying lotions and perfumes.
- Store tanzanite jewelry separately from other gemstones and jewelry to prevent scratches. A soft pouch or a lined jewelry box is ideal.
- Clean your tanzanite gently with mild soap, warm water, and a soft brush.
- Avoid exposure to harsh chemicals, extreme temperatures, and ultrasonic or steam cleaners.
- Opt for protective settings like bezels, especially for rings.
Frequently Asked Questions (FAQ)
How can I protect my tanzanite from damage?
Protecting your tanzanite primarily involves being mindful of your activities. Remove tanzanite jewelry when doing anything that could risk impact or abrasion, such as sports, gardening, or cleaning. Proper storage and choosing protective jewelry settings also significantly contribute to its longevity.
Why is tanzanite less durable than some other gemstones?
Tanzanite's lesser durability compared to gems like diamonds, rubies, or sapphires is due to its lower Mohs hardness rating (6.5-7). It also possesses distinct cleavage planes, meaning it can be more susceptible to fracturing if subjected to a sharp impact along these planes.
Can tanzanite be worn every day?
While tanzanite can be worn every day, it is advisable to do so with caution, especially if your daily routine involves activities that could expose the gemstone to scratches or impacts. For maximum longevity and to preserve its pristine condition, it's often recommended for tanzanite jewelry to be reserved for less demanding occasions or to be worn by individuals with a very gentle daily lifestyle.
What is the best way to clean tanzanite jewelry?
The safest and most effective way to clean tanzanite jewelry is by using a soft brush, a mild solution of dish soap and warm water, and then rinsing thoroughly. Dry the piece with a soft, lint-free cloth. Always avoid harsh chemicals, abrasive cleaners, ultrasonic cleaners, and steam cleaners, as these can damage the gemstone.
