Tanzanite, a captivating gemstone renowned for its intense blue-violet hues, holds a special place in the world of jewelry. Its allure has captivated hearts worldwide, making it a highly sought-after gem. However, not all tanzanite is created equal. Some undergo a heating process to enhance their color and clarity, while others retain their natural beauty. Discerning the difference between heated and unheated tanzanite is crucial for making informed purchasing decisions. This comprehensive guide delves into the intricacies of tanzanite heating, empowering you with the knowledge to recognize the natural allure of this extraordinary gemstone.
Understanding Tanzanite Heating
Tanzanite, in its natural state, often exhibits a brownish or greenish hue. To intensify the gemstone’s blue-violet color and improve its overall appearance, heating becomes a common practice. This process involves exposing tanzanite to high temperatures, typically ranging from 400 to 600 degrees Celsius, in a controlled environment. The heating process induces a chemical reaction within the gemstone, resulting in a more vibrant and saturated blue-violet color.
Identifying Heated Tanzanite
While heating can enhance tanzanite’s beauty, it’s essential to recognize that this treatment can compromise the gemstone’s natural integrity. Identifying heated tanzanite requires a keen eye and an understanding of the subtle indicators that reveal its altered state.
1. Color Saturation and Evenness
Heated tanzanite often exhibits an overly saturated and uniform blue-violet color. This stark color may appear artificial and lack the subtle variations found in naturally colored gemstones.
2. Presence of Brownish or Greenish Hues
Upon close examination, heated tanzanite may reveal remnants of its original brownish or greenish hues, particularly in areas where the heating process was uneven or incomplete.
3. Clarity and Transparency
Heating can improve tanzanite‘s clarity by reducing inclusions and enhancing transparency. However, this process may also result in a glassy or artificial appearance, lacking the depth and character of naturally occurring gemstones.
4. Fluorescence
Tanzanite’s natural fluorescence, the ability to emit visible light when exposed to ultraviolet radiation, can be affected by heating. Heated tanzanite may display a weak or absent fluorescence, while naturally colored gemstones often exhibit a strong blue or violet fluorescence.
Why Choose Naturally Colored Tanzanite?
Naturally colored tanzanite, unadulterated by heating treatments, holds several advantages over its heated counterpart:
- Preservation of Natural Beauty: Naturally colored tanzanite retains its inherent charm and individuality, showcasing the gemstone’s true essence.
- Enhanced Durability: Heating can weaken tanzanite’s structure, making it more susceptible to chipping or breakage. Naturally colored tanzanite possesses a higher degree of durability, ensuring its longevity.
- Increased Value: Naturally colored tanzanite is generally considered more valuable than heated tanzanite due to its rarity and authenticity.
Ethical Considerations
The heating of tanzanite raises ethical concerns, particularly regarding transparency and disclosure. Some jewelers may intentionally misrepresent heated tanzanite as naturally colored, misleading unsuspecting buyers. It’s crucial to purchase tanzanite from reputable sources that provide accurate information about the gemstone’s treatment history.
Caring for Your Tanzanite
Whether heated or naturally colored, proper care is essential to maintain tanzanite‘s beauty and longevity:
- Avoid Harsh Chemicals: Exposure to harsh chemicals, such as chlorine or household cleaners, can damage tanzanite. Remove your tanzanite jewelry before engaging in activities that involve contact with these substances.
- Store Safely: Store tanzanite in a soft, fabric-lined jewelry box or pouch to prevent scratches and abrasions.
- Regular Cleaning: Clean your tanzanite jewelry periodically using a mild detergent and warm water. Avoid using ultrasonic cleaners, as they can damage the gemstone.
Takeaways: Unveiling the True Beauty of Tanzanite
Tanzanite, a captivating gemstone with an allure that transcends time, offers a choice between heated and naturally colored options. Understanding the differences between these two allows you to make informed purchasing decisions, ensuring that you appreciate the true beauty and value of this extraordinary gem. Embrace the allure of naturally colored tanzanite, celebrating its inherent beauty and preserving its timeless elegance.
