Round Diamond vs. Princess Cut: Which Shape is Right for You?

When it comes to diamond shopping, the shape is one of the most important factors to consider. Among the many options available, the round diamond and the princess-cut diamond consistently rank as two of the most popular choices. But which one should you choose?

This guide breaks down the characteristics, pros and cons, and best fit for both diamond shapes to help you make an informed decision—whether you’re creating an engagement ring, a personal piece, or a meaningful gift.

Round vs Princess-Cut Diamonds

Understanding the Shapes

What is a Round Diamond?

The round diamond is the classic and timeless option, boasting a brilliant cut designed to maximize light reflection. Its symmetrical circular shape enhances sparkle, making it a favorite for those who want a traditional and versatile look.

Interesting fact? Approximately 75% of all diamonds sold are round-cut, proving its enduring popularity.

What is a Princess-Cut Diamond?

The princess cut features sharp, square corners and a distinctly modern vibe. Known for its versatility, it can give a ring a sleek and contemporary aesthetic. Princess-cut diamonds are also specifically designed to offer exceptional brilliance, similar to the round diamond but in a geometric form. 

The princess cut has been gaining popularity since its debut in the 1970s, particularly among those who want a unique yet elegant look.

Comparing Round Diamonds and Princess Cuts

1. Brilliance and Sparkle

  • Round Diamond: With 58 meticulously crafted facets, the round diamond is designed to reflect light in a way that maximizes brilliance. If sparkle is your top priority, this is the ideal choice. 
  • Princess-Cut Diamond: While the princess cut is also brilliantly designed, its shape disperses light differently, offering a distinct sparkle with slightly less fire than the round diamond.

2. Durability

  • Round Diamond: The rounded edges of this diamond make it less prone to chipping. This adds a layer of durability, especially for daily wear. 
  • Princess-Cut Diamond: The sharp corners, while beautiful, are more susceptible to damage if not properly protected by a sturdy setting. 

Winner (for active wearers): Round diamond

3. Cost and Value

  • Round Diamond: Due to its popularity and the amount of raw material lost during its cutting process, the round diamond is typically the most expensive shape per carat. 
  • Princess-Cut Diamond: For budget-conscious shoppers, the princess cut offers excellent value. Its cutting process minimizes waste, making it more affordable while still delivering exceptional brilliance.
