Diamonds are known as the hardest natural substance on earth—but here’s the truth most people don’t realize:
Diamonds can absolutely break.
At Martin Busch Jewelers, we’ve seen it happen—and the good news is, it’s usually preventable with the right knowledge and care.
Hardness vs. Toughness: What Most People Get Wrong
A diamond’s strength is often misunderstood.
-
Hardness = resistance to scratching
-
Toughness = resistance to breaking or chipping
Diamonds rank a 10 on the Mohs hardness scale (they resist scratches extremely well)…
…but their toughness is not indestructible.
So, How Can a Diamond Break?
There are a few common ways this can happen:
1. Hard Impact at the Wrong Angle
A sharp blow—especially against a hard surface like tile, granite, or metal—can cause a diamond to chip or crack.
This is most likely to happen on:
-
Edges
-
Corners (especially in princess or emerald cuts)
-
Points of the stone
2. Natural Weak Points (Cleavage Planes)
Diamonds have internal grain lines called cleavage planes.
If force hits along one of these planes, the diamond can split.
This is rare—but it’s why even a very hard diamond can break under the right conditions.
3. Improper Setting or Pressure
If a diamond is:
-
Set too tightly
-
Poorly mounted
-
Under uneven pressure
…it can become vulnerable to damage over time.
That’s why proper setting and maintenance matter just as much as the stone itself.
4. Wear Over Time
Even without a single major impact, daily wear can:
-
Weaken edges
-
Create tiny abrasions
-
Increase the risk of eventual chipping
This is especially true for rings worn every day.
Which Diamond Shapes Are More at Risk?
Some shapes are naturally more vulnerable:
-
Princess cut (sharp corners)
-
Emerald cut (long edges)
-
Pear shape (pointed tip)
-
Marquise (two pointed ends)
Round diamonds are typically the most durable due to their lack of sharp corners.
How to Prevent Diamond Damage
The good news? Most diamond damage is avoidable.
Simple ways to protect your diamond:
-
Remove your ring during workouts or heavy activity
-
Avoid wearing it while cleaning or handling chemicals
-
Have your prongs checked regularly
-
Store jewelry separately to avoid contact with other pieces
