Understanding the Reasons and Causes of Black Tourmaline Breaking
An Overview of Black Tourmaline and Its Vulnerabilities
Black tourmaline, like other minerals, can break for various reasons. This article explores the causes behind its brittleness, focusing on factors such as cleavage and fracture, physical impact, temperature changes, inclusions and impurities, and improper handling. Understanding these causes can help you prevent damage to your black tourmaline pieces and enjoy their spiritual benefits in a safe manner.
Cleavage and Fracture
Complex Crystal Structure and Cleavage Planes
Black tourmaline has a complex crystal structure with no true cleavage planes. However, it can still fracture along certain planes. If enough force is applied, the stone can break along these lines, resulting in irregular cracks or fragments. This natural property of the stone makes it susceptible to breaking under pressure.
Physical Impact
Dropping and Striking
The fragility of black tourmaline means that even a minor physical impact, such as dropping or striking the stone, can cause damage. This is particularly true if the stone has inclusions or flaws that weaken its structural integrity. Even a simple bump can lead to chipping or breaking, especially if the stone is being worn as jewelry for prolonged periods.
Temperature Changes
Thermal Stress and Cracks
Rapid temperature changes can cause thermal stress in black tourmaline, leading to the formation of cracks or fractures. This risk is heightened when the stone is exposed to extreme heat or cold. For instance, if you expose a piece of black tourmaline to direct sunlight or suddenly immerse it in cold water, it may develop cracks due to thermal expansion and contraction.
Inclusions and Impurities
Weak Structural Integrity
Black tourmaline often contains impurities and inclusions that can weaken its overall structure. These flaws make the stone more susceptible to breaking under stress. Striations, which are visible patterns on the stone, are associated with planes of cleavage. These planes are prone to fracturing, making the stone brittle and fragile.
Improper Handling
Preventive Measures for Proper Care
Handling and Storage are crucial for preserving the integrity of black tourmaline. Using the stone in jewelry or placing it in areas where it may be subjected to physical shocks, such as a tabletop in a home with pets or children, can lead to damage. To prevent breakage, it is essential to handle black tourmaline with care, store it properly, and avoid exposing it to extreme conditions.
Metaphysical and Practical Considerations
Metaphysical Benefits with Practical Safety
From a metaphysical perspective, black tourmaline is considered a strong stone. While it is spiritually significant, it is also structurally fragile. The striated layers often crack or shatter during the cutting and polishing process, making it unsuitable for jewelry. In a household setting, especially with pets or small children, it is advisable to keep black tourmaline out of reach and on a sturdy base to minimize the risk of accidental damage.
Conclusion
In summary, black tourmaline's complex crystal structure and inherent brittleness make it susceptible to breaking under various conditions. By understanding the causes of its fragility, you can take appropriate precautions to protect your black tourmaline pieces and ensure their longevity. Whether it is through proper handling, storage, or placement, protecting black tourmaline is essential for both safety and preserving its unique properties.
