When buying a diamond, most people focus on carat, clarity, or color. But the real secret behind a diamond’s sparkle lies in its cut. The way a diamond is shaped and faceted directly impacts how light enters, reflects, and shines back to your eyes. In this guide, we’ll explore how round, cushion, and pear cuts affect brilliance, and which one might be right for you.
Why Diamond Cut Matters
The cut of a diamond determines how light travels inside it. A well-cut diamond will reflect light brilliantly, creating that fiery sparkle we all love. On the other hand, a poorly cut stone, regardless of size, can look dull.
The three popular cuts—round, cushion, and pear—each have unique ways of maximizing light and brilliance.
1. Round Cut Diamonds: The Sparkle Champion

2. Cushion Cut Diamonds: Vintage Glow

Brilliance: Cushion cuts combine the sparkle of a round diamond with a slightly softer, romantic glow. Their rounded corners and larger facets give them a “chunky brilliance” with flashes of light.

3. Pear Cut Diamonds: Elegant Sparkle

Final Thoughts
When choosing between round, cushion, and pear diamonds, consider how much brilliance you want, the shape that flatters your hand, and the story you want your diamond to tell. A round cut will dazzle with unmatched sparkle, a cushion cut offers vintage charm with a cozy glow, and a pear cut makes a bold yet elegant statement.
Your diamond’s brilliance doesn’t just come from carat weight or clarity—it shines brightest when cut to perfection.
