A hammer can indeed break a diamond if struck with enough force and in the right manner. Despite diamonds being the hardest natural material known, they have a crystalline structure that makes them susceptible to breaking under a sharp impact. This article explores the properties of diamonds, the mechanics of breaking them, and practical examples.
What Makes Diamonds Hard Yet Brittle?
Diamonds are renowned for their hardness, which is the ability to resist scratching. This is due to the strong covalent bonding between carbon atoms in a diamond’s lattice structure. However, this same structure makes diamonds brittle, meaning they can fracture or shatter when subjected to a sharp force.
-
Hardness vs. Brittleness: While diamonds can scratch almost any material, they are not immune to breaking. Their hardness is measured on the Mohs scale at 10, but their brittleness means they can be cleaved along specific planes.
-
Crystalline Structure: Diamonds have a crystal lattice that is highly ordered. This structure allows for planes of weakness, known as cleavage planes, where the atomic bonds are weaker.
How Can a Hammer Break a Diamond?
Is It Possible to Break a Diamond with a Hammer?
Yes, a hammer can break a diamond if it hits the diamond along its cleavage planes. This requires precise force and angle.
-
Cleavage Planes: Diamonds can be split along these natural planes. Jewelers use this property to cut diamonds into shapes.
-
Impact Force: A hammer delivers a concentrated force that, if aligned with a cleavage plane, can cause the diamond to fracture.
Practical Example: Diamond Cutting
In the diamond industry, professionals use tools to cleave diamonds along these planes. This process involves:
- Marking the Diamond: Identifying the cleavage planes.
- Scoring: Making a small incision along the plane.
- Applying Force: Using a tool to apply force, similar to a hammer strike, to split the diamond.
Why Do Diamonds Break Under Impact?
What Factors Influence a Diamond’s Breakability?
Several factors affect whether a diamond will break when struck:
- Size and Shape: Larger diamonds with irregular shapes may have more vulnerable points.
- Quality and Flaws: Inclusions or internal flaws can weaken a diamond’s structure.
- Force Direction: The direction and angle of the impact relative to the cleavage planes are crucial.
Can All Diamonds Be Broken Easily?
Not all diamonds will break easily. High-quality diamonds with fewer inclusions and a well-cut shape are more resistant to breaking.

How Do Jewelers Cut Diamonds?
Jewelers cut diamonds using a combination of sawing, cleaving, and polishing. They carefully plan each cut to maximize the diamond’s brilliance and minimize waste. The process involves identifying the natural cleavage planes and using precise tools to split and shape the diamond.
Are Diamonds the Hardest Material?
While diamonds are the hardest natural material, there are synthetic materials, like aggregated diamond nanorods, that are harder. However, diamonds remain unmatched in their natural state for hardness.
Can Diamonds Be Damaged by Everyday Wear?
Yes, diamonds can be chipped or cracked if struck against a hard surface. Though they are durable, it is advisable to handle them with care, especially in jewelry settings.
What Is the Difference Between Hardness and Toughness in Diamonds?
Hardness refers to a diamond’s ability to resist scratching, while toughness is its ability to withstand breaking or chipping. Diamonds are hard but not particularly tough due to their brittle nature.
How Can You Protect a Diamond?
To protect a diamond, avoid exposing it to sharp impacts, store it separately from other jewelry, and have its settings checked regularly by a jeweler.
Conclusion
In summary, while diamonds are extremely hard, they can be broken by a hammer if struck correctly along their cleavage planes. Understanding the properties of diamonds, such as their hardness and brittleness, helps explain why they can be both incredibly durable and surprisingly fragile.
