Can A Diamond Chip Or Break?

Diamonds are often described as the hardest material on Earth. That’s true — but hardness isn’t the same as indestructibility. While diamonds resist scratches better than any other gemstone, they can still chip or break under certain conditions.

At Mervis Diamond Importers, we believe in educating our clients so you not only admire your diamond’s brilliance but also understand how to protect it for generations to come.

Hardness vs. Toughness — Why the Difference Matters

  • Hardness: Diamonds score a perfect 10 on the Mohs scale. This means nothing can scratch a diamond except another diamond.

  • Toughness: Toughness measures resistance to breaking or chipping. Diamonds, while hard, have natural crystal planes that make them brittle at certain angles.

Key point: Diamonds resist scratches exceptionally well but can chip if struck in the wrong place.

When Can a Diamond Chip or Break?

Even the most brilliant stone isn’t immune to impact. Common situations include:

  • Accidental knocks: Hitting your ring against granite countertops or ceramic tiles.

  • Sharp blows: Dropping your diamond jewelry on a hard floor.

  • Weak points: Corners of fancy shapes (princess, marquise, pear) are more vulnerable than round brilliants.

  • Thin girdles: A very thin girdle can make a diamond more fragile along its edge.

Which Diamonds Are More at Risk?

Not all diamonds carry the same risk. Factors that increase vulnerability include:

  • Clarity features: Large inclusions or feather-like fractures near the surface can weaken the stone.

  • Shape: Sharp corners (emerald, princess) are prone to chipping; rounded shapes (oval, round) are safer.

  • Mounting style: Exposed settings, like tension mounts, leave more of the diamond vulnerable to impact.

Can a Chipped Diamond Be Fixed?

Yes — but with considerations.

  • Polishing: Small chips may be polished away, but this reduces carat weight.

  • Re-cutting: Larger chips may require re-cutting to restore beauty, sometimes altering shape.

  • Replacement: In severe cases, replacement may be the best option.

At Mervis Diamond Importers, our experts can evaluate whether repair or replacement is the most appropriate solution for your diamond.

How to Protect Your Diamond

Diamonds are timeless, but care ensures they stay pristine.

  • Choose a protective setting: Bezels or halo settings shield vulnerable edges.

  • Insure your diamond: Comprehensive jewelry insurance covers accidental damage.

  • Regular inspections: Have your prongs, setting, and stone checked every 6–12 months.

  • Mindful wear: Remove rings during heavy lifting, sports, or high-impact activities.

FAQs About Diamond Durability

Can a diamond break in half?

It’s rare, but a strong impact at a cleavage plane can cause a diamond to split.

Do small diamonds chip less easily?

Yes, smaller stones are generally less vulnerable because they have fewer exposed edges.

Can lab grown diamonds chip too?

Yes. Lab grown diamonds share the same atomic structure as natural ones, so they carry the same risks and require the same care.

Conclusion: Diamonds Are Forever — With Care

So, can a diamond chip or break? Yes, but only under unusual stress. Diamonds remain the hardest natural material known, and with the right setting, care, and protection, yours will last for generations.

At Mervis Diamond Importers, we’ll guide you not only in selecting the perfect diamond but also in safeguarding it — whether through custom settings, expert inspections, or repair services when needed.
