Diamonds are often hailed as the hardest natural substance known to man, leading many to believe they're indestructible. But what happens if you hit a diamond with a hammer? Can something so incredibly hard be shattered by a simple blow? In this article, we'll delve into the fascinating world of diamonds, their unique properties, and answer the pressing question: Can you break a diamond with a hammer?
Understanding Diamond Hardness vs. Toughness
Hardness and toughness are two different material properties that often get conflated. Hardness refers to a material's ability to resist scratching, while toughness is about how well a material can absorb energy and resist fracturing.
Diamonds rank 10 on the Mohs scale of mineral hardness, making them the hardest natural material. This means that they can scratch all other substances but are not necessarily resistant to breaking or chipping.
What Makes Diamonds the Hardest Natural Substance?
The structure of the diamond is a repeating lattice of carbon atoms bonded together with strong covalent bonds. Each carbon atom shares electrons with four other carbon atoms, creating a rigid and incredibly strong three-dimensional network. This atomic arrangement is what gives diamonds their exceptional hardness.
Is It Possible to Break a Diamond with a Hammer?
Yes, it is indeed possible to break a diamond with a hammer. While diamonds are incredibly hard, they are also brittle. If you hit a diamond with a hammer, especially at the right angle, it can cleave or shatter.
The toughness of diamond is relatively low compared to its hardness. This means that while it resists scratches from other materials, a sharp blow can cause it to fracture.
The Role of Cleavage Planes in Diamond Breakage
Diamonds have distinct cleavage planes, which are directions in the crystal structure where the bonds between carbon atoms are weaker. Striking a diamond along these planes makes it easier to break.
Diamond cutters exploit these planes to shape diamonds, using tools to precisely apply force along these lines. This is how rough diamonds are transformed into the dazzling gems we see in jewelry.
Diamond Cutting: How Do Diamond Cutters Work?
Diamond cutting is a meticulous process that involves cleaving, cutting, and polishing. Diamond cutters use specialized tools, often embedded with diamond dust, to cut along the cleavage planes.
The process requires precision because applying too much force or striking at the wrong angle can result in unwanted fractures or even shattering the diamond.

Comparing Diamonds to Other Hard Materials
While diamonds are the hardest natural substance, they are not the toughest. Materials like steel and certain ceramics have higher toughness, meaning they are less likely to break under impact.
For instance, sapphire is another hard material but is more resistant to fracturing than diamond. This distinction is crucial in applications requiring materials that can withstand both scratching and impact.
Practical Implications: Should You Worry About Breaking Your Diamond Jewelry?
While it's theoretically possible to break a diamond, in practical terms, your diamond jewelry is unlikely to shatter under normal wear. However, diamonds can chip or cleave if struck hard enough or at the right spot.
To protect your diamonds:
- Avoid wearing diamond rings during activities that involve hard impacts.
- Regularly inspect your jewelry for signs of damage.
- Ensure settings are secure to prevent stones from coming loose.
FAQs About Diamonds and Durability
Can a Diamond Scratch or Break Another Diamond?
Yes, only a diamond can scratch another diamond due to their hardness. Additionally, diamonds can cause chipping or damage to each other if they collide.
Are Diamonds Indestructible?
No, diamonds are not indestructible. They are hard but also brittle, making them susceptible to breaking under certain conditions.
What Amount of Force Does It Take to Break a Diamond?
The force required varies depending on the diamond's size and shape and the direction of the force relative to its cleavage planes. A sufficiently hard blow at the right angle can cause a diamond to fracture.
Protecting Your Diamonds: Tips and Advice
- Be Mindful: Remove diamond jewelry during heavy work or sports.
- Regular Cleaning: Keep your diamonds clean to spot any potential issues early.
- Professional Inspections: Have a jeweler check your settings and stones periodically.
