Do Diamonds Crack or Break?

Summary

Yes, diamonds can crack or break under certain conditions, despite being the hardest natural material. While their hardness makes them resistant to scratching, diamonds also have natural planes of weakness called cleavage lines, which means a strong impact at the right angle can cause chips, cracks, or even breaks. With proper care and setting, however, diamonds are highly durable and can last for generations.


Diamonds are celebrated for their unmatched durability, but many people wonder if they’re truly unbreakable. The truth is that while diamonds are incredibly strong, they are not indestructible.

Below, we’ll explore how diamonds can sustain damage, what causes cracks, and how to protect your stone for long-lasting beauty.

How Diamonds Can Crack or Break

Diamonds can crack or break when subjected to sharp impacts or pressure along their natural cleavage planes.

This is because diamonds are the hardest substance on the Mohs scale (resistant to scratching), but hardness is different from toughness (resistance to breaking). For this reason, a diamond can survive daily wear but still chip if struck at a vulnerable angle.

Common causes of diamond damage include:

  • Impact: Dropping or striking the stone against hard surfaces.
  • Pressure: Applying force along cleavage planes during wear or repairs.
  • Poor setting protection: Prongs that don’t shield vulnerable edges or corners.

Protecting Your Diamond from Damage

Although diamonds can break, proper care and protective settings greatly reduce the risk.

Jewelers often recommend protective settings—like bezels or halo designs—to safeguard the diamond’s edges. Regular maintenance, inspections, and safe storage also ensure that the stone remains intact and brilliant for years.

Hardness measures scratch resistance, while toughness refers to resistance against breaking or chipping.

3. Can a chipped diamond be repaired?
In many cases, jewelers can recut or reshape a chipped diamond, though it may lose some carat weight.

4. Are lab-grown diamonds less durable than natural diamonds?
No, lab-grown diamonds have the same hardness and durability as natural diamonds.

5. How often should I have my diamond ring checked?
It’s recommended to have it inspected every 6–12 months to ensure the setting is secure and the diamond is protected.
