Could a Fingernail Scratch a Diamond Ring?

We’ve all heard of the old adage about diamonds being forever, but the truth is that diamonds are not entirely invincible. However, does this mean something as minor and unassuming as a fingernail could actually scratch a diamond ring?

It’s impossible to scratch a diamond ring with a fingernail. The Mohs’ Scale of Mineral Hardness indicates that diamonds are the hardest mineral and can only be scratched by another diamond. But although diamonds may seem virtually indestructible, they can still suffer from chip damage.

In this article, we’ll dive into the mystery of why fingernails can’t scratch a diamond and reveal some fascinating insights into why diamonds are so tough. You’ll also learn tips on caring for diamond rings to protect their brilliance and beauty over the long haul. With this in mind, let’s begin.

Is It Easy To Accidentally Scratch a Diamond?

Largely regarded as a symbol of strength and eternity, diamonds are incredibly durable gemstones. But is it easy to accidentally scratch a diamond? The answer might surprise you.

Although diamonds may be the hardest mineral on Earth, they’re not impervious to scratching. A harder material can and will scratch most gemstones since their molecular structure consists of tiny crystalline particles. 

That said, it’s pretty unlikely that you’ll accidentally scratch a diamond unless you’re actually trying to do so!

Mohs’ Scale of Mineral Hardness

When determining the hardness of minerals, professionals use the Mohs’ Scale of Mineral Hardness to measure which mineral can be scratched by another mineral. 

On this scale, diamonds come out on top as they’re the hardest mineral and can only be scratched by another diamond. So when it comes to diamond rings, your fingernail won’t be able to do any damage.

Chip Damage Risk

Though diamonds may appear virtually indestructible, they can still suffer from chip damage due to pressure or external force. 

So if you have a diamond ring that’s exposed to external stress, such as while playing sports or using heavy-duty tools, you need to take certain precautions to prevent accidental chipping.

Protecting Your Diamond Jewelry

Proper care and maintenance is the most effective way to keep your diamond jewelry safe from accidental scratches and chips. Here are some tips to remember:

  • Store your rings separately in protective cases. This will reduce the chance of friction between pieces and the potential for scratching.
  • Clean regularly with a mild soap solution or warm water. This will help remove dust particles and oils that may cause build-up over time.
  • Avoid exposing your stones to extreme temperatures. Sudden temperature changes cause expansion and contraction in metal settings which could lead to loosening prongs and possible stones falling out.

Though diamonds are incredibly hardy gems, these simple steps in caring for your jewelry will ensure its brilliance and beauty stay intact.

What Makes a Diamond So Durable?

We often hear about the beauty and value of diamonds but rarely about their durability. So what makes them so strong and resilient? Let’s take a closer look at why diamonds have become such an integral part of our culture (and some useful tips for buying them!)

The Hardness of a Diamond

A diamond is made up of carbon atoms arranged in a unique crystalline structure known as the ‘diamond lattice.’ This structure gives diamonds incredible strength, which makes them incredibly difficult to break or scratch. 

Diamonds are ten times harder than any other naturally-occurring material on Earth! So when it comes to hardness, no other gemstone even comes close to a diamond’s impressive properties.

Why Are Diamonds So Valuable?

Because diamonds are so durable and highly sought after, they come with a hefty price tag. In addition to the rarity of these gems, the perception of luxury is also associated with them. 

Many consider owning a diamond a sign of wealth and good taste – they make excellent investments too! Furthermore, many believe that diamonds signify everlasting love and commitment – hence their popularity as engagement rings.

Tips for Buying a Diamond

If you’re looking to purchase one (or more) of these precious stones, here are some pointers that could help you save money:

  • Consider purchasing online rather than from a physical store. You might get better value for money this way if you compare prices thoroughly.
  • Look for GIA or AGS-certified stones. These certificates ensure that your diamond meets the highest standards.
  • Ask about ‘clarity enhancements.’ Specific treatments can help improve a diamond’s appearance and overall value.
  • Remember carat weight. If possible, choose larger stones because they usually cost less per carat.
  • Shop around before deciding. Compare different styles, colors, and shapes before settling on one stone.
  • Always inspect the diamond before buying. Ensure it has no visible defects or blemishes.
  • Investigate the store’s return policy. If you’re unsatisfied with your purchase, it’s best to know your options.
  • Ask about trade-ins and upgrades. Some stores may allow you to upgrade or exchange your diamond after a certain time.

Does the Cut of the Diamond Influence Its Strength?

Have you ever wondered how the cut of a diamond influences its strength and durability? 

It may come as a surprise, but the cut impacts how resilient your precious stone will be. Before you make your next diamond purchase, consider these key factors that affect strength: 

  • Size 
  • Shape
  • Angles
  • Facets

Let’s explore them in a little more detail:

Size and Shape

A diamond’s size and shape can affect its durability – larger diamonds are more susceptible to chipping than small stones due to their weight. 

Additionally, certain shapes may not provide enough protection against fractures: marquise-shaped diamonds are especially prone to breakage due to their pointed tips.


How a diamond is cut makes all the difference regarding resilience. Different angles ensure that light reflects properly off each facet. 

If the angles are too steep or shallow, they could fail to reflect any light or, worse yet, cause brittle points on either end where chipping might occur. The perfect combination offers the maximum brilliance and protects against damage.


Faceted diamonds are much less likely to chip or crack than cabochons (smooth-surfaced stones with no facets). That’s because facets help disperse light evenly over the entire surface area. 

So if you’re looking for a particularly strong stone for your jewelry collection, opt for one that offers multiple reflections from various directions – it may look dazzling but still provide essential protection.

Home Remedies To Repair Hairline Diamond Scratches

It’s not easy to scratch or damage a diamond ring, but it can happen. When it happens, many people first want to know if there are ways to repair hairline scratches at home. 

For some, the idea of paying for expensive repairs seems unbearable, but there are DIY solutions that can help restore your diamond ring with minimal effort and cost. Let’s explore your options.

Steps To Properly Clean Your Diamond Ring

Before you can repair a scratch on your diamond ring, you must take time to clean your jewelry correctly. Here are some steps you can take:

  1. Put on a pair of rubber gloves before handling your diamond ring.
  2. Use lukewarm water and mild soap to remove any dirt or debris from the stone.
  3. Rinse the diamond off with distilled water and let it air dry. Make sure not to use harsh chemicals or abrasives as they can damage its surface.

Can You Repair Hairline Scratches at Home?

Once you’ve taken proper cleaning measures, you can address the scratch itself. The good news is that minor hairline scratches can be repaired at home with just a few materials. 

Here are some valuable tips for light surface scratches:

  • Fetch a slightly abrasive cloth (like an old T-shirt).
  • Gently buff out the scratch with a back-and-forth motion until it is no longer visible. 
  • Dip a Q-tip in rubbing alcohol and dab it on top of the scratch to reduce its visibility even more. (Rubbing alcohol also works well for removing superficial smudges found on diamonds.)

When You Need Professional Repair Services

Suppose you’ve tried these methods and still need help repairing your diamond ring. In that case, it might be time for professional help from an experienced jeweler specializing in diamond and gemstone repair services. 

They’ll determine if the stone needs polishing or re-setting to restore its original appearance. Both processes require additional fees, but they’re worth it if the ring holds value for you. 

Professional Cleaning and Re-Setting

Professional cleaning and re-setting of jewelry is a process that helps keep your pieces looking their best. It involves restoring the shine on your favorite pieces and ensuring that every component is securely in place, helping you avoid further damage. 

There are many advantages to having your jewelry professionally cleaned and re-set. Here are some of the most important ones:

  • Enhanced beauty: Professional cleaners can remove tarnish, dirt, and other grime from your jewelry to make it look as good as new. They can also use polishing techniques to bring out gems and metals’ brilliance.
  • Secure settings: Through careful inspection, professional jewelers can ensure that all clasps, settings, stones, bands, etc., remain secure at all times. This peace of mind is invaluable when wearing such precious items.
  • Restored integrity: As with any delicate item, jewelry wears over time due to everyday use or exposure to certain elements. However, professional cleaning and re-setting can help restore its strength so it stands up to daily wear better than ever before.

Why It’s Important To Check Your Diamonds for Damage

We all love to spoil ourselves with jewelry: the glimmer of a necklace, the sparkle of a pair of earrings, and the shine of a ring. But over time, our jewelry can take some serious damage – without us even noticing. That’s why it’s so important to get your diamonds checked up by an expert occasionally.

Here’s why:

  • Avoid further damage: When you get jewelry checked regularly, any minor issues that could cause further deterioration in the future can be spotted and resolved quickly before they have a chance to become more significant problems.
  • Keep up appearances: Even if there aren’t any significant issues with your jewelry, it may still lose its luster or sparkle over time due to everyday wear and tear. Fortunately, regular checkups allow your jeweler to give your pieces a bit of extra polish or buffing so they look as good as new.
  • Guarantee safety: Many different types of jewelry come with delicate clasps and settings that need to be inspected periodically to guarantee their safety and security. This is especially important if there’s been an accident involving the piece in question or if it’s been exposed to moisture or other elements which could degrade its structural integrity over time.

Your Jeweler Can Help

Getting your jewelry checked doesn’t have to be complicated. Plenty of experienced jewelers will be more than happy to inspect all sorts of items, from rings and necklaces to watches and bracelets. 

Whatever type of jewelry you have, chances are there’s someone who can help keep it looking its best. Moreover, all these services typically only require a small fee, so there’s no need to worry about spending too much. 

Jewelry isn’t just something we own for a short while; it’s something we can treasure for many decades to come, just as long as we take good care of it.

Make sure you get professional help with caring for yours by taking it in for checkups every once in a while. That way, you’ll always have those unique pieces in pristine condition, no matter how long they’ve been part of your collection.

Final Thoughts

It’s fascinating to think about the incredible strength of diamond rings. They can survive all sorts of wear and tear and even a few accidents along the way. Moreover, a sharp fingernail is unlikely to cause any visible damage either.

However, it’s important to remember that they still need to be cared for and inspected occasionally. That’s why checking your diamonds with a professional is so important – it ensures that you can keep the pieces you love looking their best. 

So don’t be afraid to show your jewelry some extra care now and then. After all, keeping your diamond ring looking as remarkable and dazzling as when you first received it – is well worth it!
