Choosing a diamond shape involves more than just appearance. One of the key factors that gets overlooked is how strong and long-lasting the shape is. Even though diamonds are hard, their shape can affect how likely they are to chip, crack, or get damaged during regular use.
Let us compare the durability of fancy diamond shapes with the classic round cut and see how they hold up.

Why the Round Cut Is Stronger
The round cut is widely used in jewelry, especially rings, for a reason. It is the most balanced shape with no corners or sharp ends. This structure gives it better strength against impact.
Since there are no weak points, pressure gets spread evenly throughout the stone. This makes it more resistant to chipping. Also, during the cutting process, parts of the diamond that may be more likely to break are removed. As a result, the round cut ends up being more reliable than most fancy shapes.
What Are Fancy Diamond Shapes?
Let’s look at each fancy diamond shape and see how it compares to the round cut in terms of toughness.
Princess Cut
The princess cut is square or rectangular with sharp corners. These corners are the weak points. If hit directly, they can chip or break.
If the setting covers these corners, it can reduce the chance of damage. But the shape still carries more risk than a round cut.
Marquise Cut
This shape has two pointed ends. These tips are the most fragile areas. A bump or knock can easily lead to chipping.
To protect the shape, prongs are used at each tip. Still, the risk remains higher than with round shapes.
Pear Cut
The pear shape has one rounded end and one pointed end. The tip is delicate and may chip with daily wear.
This shape needs a strong setting to guard the point. Otherwise, it may not last long if worn every day.
Oval Cut
The oval shape has no points, which helps it resist damage better than marquise or pear cuts. It is longer than a round shape, so it may be slightly more open to impact along the sides.
Still, it has fewer weak points, and that makes it a better option in terms of strength among fancy shapes.
Conclusion
The round cut remains the top choice for those who want strength and durability. Its shape offers fewer chances for chips or cracks. Fancy shapes may look different, but most have sharp edges, long sides, or points that raise the risk of breakage. Pick the diamond shape based on where and how often it will be worn. That will help you make a better choice that lasts longer without issues.
