Blue sapphires are one of the most beautiful and sought-after gemstones in the world. Their rich, deep blue hue makes them a popular choice for engagement rings, necklaces, earrings, and other fine jewelry. However, before purchasing blue sapphire jewelry, many people wonder about the durability of these precious stones. Specifically, one common question is whether blue sapphires scratch easily. In this article, we will dive deep into the characteristics of blue sapphires, their scratch resistance, and how to take care of them to keep them looking as stunning as the day you bought them.
What Are Blue Sapphires?
Blue sapphires belong to the corundum family of gemstones, which also includes rubies. The intense blue color of sapphires is due to the presence of trace elements such as iron and titanium. Sapphires can occur in a variety of colors, but blue sapphires are the most popular and well-known type.
The Hardness of Blue Sapphires: A Key to Their Durability
One of the most important factors to consider when discussing the scratch resistance of blue sapphires is their hardness. Blue sapphires are rated 9 on the Mohs scale of mineral hardness. This scale measures the ability of a mineral to resist scratching by other substances. A gemstone with a higher number on the Mohs scale is harder and more scratch-resistant than one with a lower number.
On the Mohs scale, diamonds are rated as 10, making them the hardest known natural material. Blue sapphires, with their rating of 9, are very hard but slightly softer than diamonds. While they are resistant to most scratches, they are not entirely immune to damage from harder substances.
Factors That Affect the Scratch Resistance of Blue Sapphires
While blue sapphires are known for their durability, several factors can affect their resistance to scratches. Understanding these factors can help you take proper care of your sapphire jewelry and maintain its appearance over time.
1. The Quality of the Sapphire
The quality of the sapphire can impact its overall durability. High-quality sapphires, with fewer inclusions (internal flaws), are less likely to have weak spots that could make them more prone to scratching. In contrast, sapphires with visible inclusions or fractures may be more vulnerable to damage.
2. The Type of Sapphire Cut
The way a sapphire is cut can also influence its scratch resistance. Faceted sapphires are typically more durable than cabochon-cut sapphires, which are rounded and polished. Faceting creates more surfaces that distribute pressure more evenly, while a smooth, rounded shape may concentrate pressure in certain areas, potentially making them more susceptible to scratches.
3. Exposure to Harder Materials
Despite being relatively scratch-resistant, blue sapphires can be scratched by materials that are harder than them, such as diamonds. It’s essential to keep sapphire jewelry away from other gemstones with a higher Mohs rating, especially diamonds.
4. Everyday Wear and Tear
The daily activities and environments you expose your sapphire jewelry to can also affect its scratch resistance. For instance, wearing sapphire rings while doing household chores, exercising, or engaging in activities where they may come into contact with hard surfaces like countertops or floors can lead to scratches.
Are Blue Sapphires Prone to Scratching?
While blue sapphires are not as easily scratched as softer gemstones, they can still be vulnerable under certain conditions. Although they are quite durable, they are not indestructible. The likelihood of a sapphire scratching depends on how it is treated and the environment in which it is worn.
How to Prevent Scratches on Your Blue Sapphire Jewelry
To keep your blue sapphire jewelry looking pristine for years to come, it is essential to care for it properly. Here are some tips on how to prevent scratches and maintain the beauty of your sapphire jewelry.
1. Remove Jewelry When Engaging in Physical Activities
One of the best ways to prevent scratches is by removing your sapphire jewelry when engaging in physical activities. This includes exercise, cleaning, gardening, or any activity that may expose your jewelry to dirt, harsh chemicals, or impact.
2. Store Sapphire Jewelry Properly
When you’re not wearing your sapphire jewelry, store it properly to avoid scratches. Keep it in a separate compartment in your jewelry box or use a soft cloth pouch to protect it from other jewelry and hard surfaces.
3. Clean Sapphire Jewelry Carefully
Cleaning your sapphire jewelry is essential to maintain its brilliance. However, cleaning it too roughly can lead to scratches. Use a soft cloth or a gentle jewelry cleaning solution to clean your sapphire. Avoid using abrasive materials or harsh chemicals.
4. Avoid Contact with Hard Surfaces
Be mindful of where you place your sapphire jewelry. Avoid placing it on hard surfaces like granite, marble, or glass, as these can cause scratching. It’s also advisable not to store sapphire jewelry in a jewelry box that contains other harder stones.
Common Misconceptions About Blue Sapphire Durability
There are several misconceptions about blue sapphire durability that can lead to confusion when it comes to caring for this precious gemstone. Let’s take a look at a few of the most common myths.
1. Blue Sapphires Are Completely Scratch-Proof
While blue sapphires are highly scratch-resistant, they are not completely scratch-proof. They can still be damaged if exposed to extremely hard substances, such as diamonds. However, compared to most other gemstones, blue sapphires are quite durable and resistant to daily wear and tear.
2. Only Diamonds Are Resistant to Scratching
Diamonds are indeed the hardest known material, but they are not the only stones that are highly resistant to scratching. Blue sapphires, with their Mohs rating of 9, are incredibly durable and will not scratch easily under normal conditions.
3. Sapphires Can’t Be Damaged at All
Though blue sapphires are hard and durable, they can still be damaged if they are exposed to significant force or subjected to impacts that cause fractures or chips. Always handle sapphire jewelry with care to ensure its longevity.
Conclusion
Blue sapphires are among the most durable gemstones available, ranking 9 on the Mohs scale of hardness. They are highly resistant to scratches but not entirely impervious to damage. To keep your sapphire jewelry looking beautiful, it’s important to handle it with care, store it properly, and avoid contact with harder materials.
By understanding the factors that contribute to a sapphire’s scratch resistance and following the best practices for care and maintenance, you can ensure that your blue sapphire jewelry remains a stunning part of your collection for many years to come.
