Black tourmaline is a striking gemstone known for its deep, rich color and its metaphysical properties. Many people are drawn to this stone for its beauty and the belief that it can offer protection from negative energy. But when it comes to jewelry, the question often arises: Does black tourmaline break easily?
The durability of any gemstone is one of the most important factors in determining whether it is suitable for daily wear, especially when set in jewelry. Understanding the hardness, toughness, and overall resilience of black tourmaline will help you determine how best to care for it.
What is Black Tourmaline?
Before we dive into the durability of black tourmaline, let’s take a closer look at the gemstone itself. Black tourmaline, also known as Schorl, is a member of the tourmaline family, which is a complex group of boron silicate minerals. It is one of the most well-known and widely used varieties of tourmaline.
The mineral is typically dark black or deep brown in color but can also be found in shades of green, blue, and pink in other varieties. Black tourmaline, specifically, has been prized for its unique appearance and its supposed ability to protect against negative energies, making it a popular choice for amulets, bracelets, pendants, and other jewelry items.
Black Tourmaline’s Hardness
In order to understand whether black tourmaline breaks easily, we need to consider its hardness. Hardness refers to a mineral’s resistance to scratching and abrasion. The Mohs scale of mineral hardness is commonly used to measure this property, with 1 being the softest (talc) and 10 being the hardest (diamond).
Black tourmaline has a Mohs hardness of 7 to 7.5, making it relatively hard compared to many other gemstones. For reference, quartz, a common mineral, has a hardness of 7, while sapphire, known for its strength, is rated 9. The hardness of black tourmaline means it can withstand some scratching and wear, but it is not as resistant to damage as diamonds, sapphires, or rubies.
While a Mohs hardness of 7 to 7.5 indicates that black tourmaline can handle typical daily wear and tear, it is important to remember that hardness is not the only factor affecting the gemstone’s durability.
Black Tourmaline’s Toughness
Toughness refers to a gemstone’s ability to resist breaking, chipping, or fracturing. A gem can be hard but still be prone to shattering if subjected to a hard blow or stress. Black tourmaline, while relatively hard, is considered to have moderate toughness. It is not as tough as some other stones like jade or sapphire, which are known for their resistance to cracking or breaking.
One of the challenges with black tourmaline, and tourmaline in general, is that it can have natural inclusions or fractures within the stone. These internal imperfections can make the gemstone more prone to breaking if subjected to strong impact. For this reason, black tourmaline jewelry, especially larger pieces or those set in rings, must be worn with care to avoid sudden impacts that could cause fractures.
Factors Affecting Durability
Several factors can influence how easily black tourmaline breaks.
Let’s examine some of the key elements:
1. Setting and Shape of the Gemstone
The way a black tourmaline gemstone is set in jewelry can affect its durability. Stones set in rings or bracelets are more vulnerable to impact, especially if they are exposed or have a sharp corner. Stones that are bezel-set, where the metal surrounds the edges of the stone, tend to be better protected from knocks.
Additionally, the shape of the gemstone matters. A round or oval shape is generally less prone to chipping compared to stones with sharp edges, like square or princess cuts. The more angles a stone has, the more likely it is to develop fractures when subjected to force.
2. Environmental Factors
Environmental factors, such as temperature and humidity, can also affect the durability of black tourmaline. Extreme temperature changes can cause thermal shock, which may cause cracks or fractures in the stone. Similarly, exposure to chemicals or harsh cleaning agents can weaken the gemstone over time.
3. Impact and Wear
While black tourmaline is not as fragile as some other stones, it is still susceptible to damage from physical impact. Jewelry items like rings, which are exposed to frequent contact with hard surfaces, are more prone to damage. Similarly, wearing black tourmaline jewelry while performing physical activities like sports or heavy lifting can increase the risk of breaking the stone.
4. Inclusions and Natural Defects
As mentioned earlier, black tourmaline, like many gemstones, may contain inclusions. These natural imperfections can weaken the stone’s structural integrity. If a gemstone has visible cracks, voids, or internal fractures, it is more likely to break or chip under pressure.
How to Care for Black Tourmaline Jewelry
Caring for black tourmaline jewelry is essential to preserving its beauty and preventing damage.
Here are some tips for taking good care of your black tourmaline jewelry:
1. Avoid Impact
To minimize the risk of breaking or chipping your black tourmaline, avoid situations where the stone may be subjected to impact. For example, take off your jewelry when engaging in physical activities like exercise or sports. It’s also a good idea to remove rings before doing household chores, as they may come into contact with hard surfaces.
2. Clean Gently
When cleaning black tourmaline jewelry, use a soft cloth or brush to remove dirt and dust. Avoid using harsh chemicals or abrasive materials that could scratch the surface of the stone. A mild soap and warm water solution is typically sufficient for cleaning.
3. Store Carefully
When you’re not wearing your black tourmaline jewelry, store it in a soft pouch or jewelry box to prevent it from coming into contact with other harder gemstones or objects that could scratch it. If you’re storing rings or bracelets, consider placing them in individual compartments to avoid rubbing against each other.
4. Regular Inspections
It’s a good idea to have your black tourmaline jewelry inspected periodically, especially if it’s set in a ring or bracelet. Check for any signs of cracks, loose settings, or damage. If you notice any issues, it’s best to have the jewelry repaired promptly to prevent further damage.
Is Black Tourmaline Suitable for Everyday Wear?
Black tourmaline is a reasonably durable gemstone, but whether it is suitable for everyday wear depends on how it is set and how carefully it is maintained. If you choose a well-set piece of jewelry and take precautions to protect the stone, black tourmaline can last for many years without breaking or chipping. However, if you’re planning to wear black tourmaline jewelry regularly, it’s important to consider its moderate toughness and the potential for damage from impact or stress.
For people who wear rings, bracelets, or necklaces with black tourmaline every day, proper care is essential to maintain the gemstone’s appearance and prevent it from breaking. Choosing a protective setting and removing the jewelry when engaging in physical activities will go a long way in preserving the stone.
Conclusion
Black tourmaline is a stunning gemstone with a moderate level of durability. While it is not as tough as some other gemstones, its Mohs hardness of 7 to 7.5 ensures that it can withstand everyday wear under normal conditions. However, the stone’s natural inclusions and moderate toughness make it susceptible to breaking if exposed to strong impacts or stress.
By taking proper care of black tourmaline jewelry, including avoiding impact, cleaning gently, and storing it carefully, you can enjoy this beautiful gemstone for many years without worrying about it breaking easily.
In summary, black tourmaline does not break easily under normal wear, but like any gemstone, it requires mindful care to maintain its beauty and longevity.
