Sapphires are renowned for their exceptional hardness and durability, making them a popular choice for various applications, from fine jewelry to watch crystals. However, a common question arises: Can sapphires be scratched? Let's delve into the properties of sapphires to answer this question.
Understanding Sapphire Hardness
Sapphires belong to the corundum family and rank 9 on the Mohs hardness scale, which measures a mineral's resistance to scratching. This positions sapphires just below diamonds, the hardest known natural material with a rating of 10. The Mohs scale is ordinal, meaning each level is not equidistant; for instance, diamonds are significantly harder than sapphires, despite being only one rank higher.
Can Sapphires Be Scratched?
While sapphires are incredibly hard and resistant to scratches, they are not entirely scratch-proof. Materials that are equal to or harder than sapphires on the Mohs scale can scratch them. The most common substances capable of scratching a sapphire include:
Diamonds: With a Mohs hardness of 10, diamonds can scratch sapphires.
Other Sapphires or Rubies: Since rubies are also corundum with a hardness of 9, they can scratch sapphires.
In everyday situations, it's uncommon to encounter materials harder than sapphires. However, certain scenarios can lead to scratches:
Contact with Diamond Jewelry: If sapphire jewelry comes into contact with diamonds, there's a risk of scratching.
Abrasive Materials: While rare, some industrial abrasives or accidental contact with materials containing hard particles could potentially scratch sapphires.
Durability Beyond Hardness
It's important to note that while sapphires are highly scratch-resistant, they can still be susceptible to chipping or fracturing if subjected to hard impacts. Their crystalline structure, though hard, can be brittle under significant force.
Caring for Your Sapphire Jewelry
To maintain the luster and integrity of your sapphire pieces:
Avoid Hard Impacts: Be cautious to prevent dropping or striking your sapphire jewelry against hard surfaces.
Store Separately: Keep sapphires separate from diamonds and other gemstones to prevent potential scratching.
Regular Cleaning: Clean your sapphires with mild soapy water and a soft brush. Avoid harsh chemicals that could damage the stone or its setting.
Conclusion
Sapphires offer a remarkable combination of beauty and durability, making them suitable for daily wear. While they are highly resistant to scratches, it's essential to handle them with care to preserve their pristine condition. By understanding their properties and following proper care guidelines, you can ensure your sapphire jewelry remains a cherished piece for years to come.
