Picking out a diamond? You’re in for a fun—but potentially overwhelming—journey. Beyond size and color, one of the most important (and exciting!) choices you’ll make is the cut. The cut affects not just how your diamond looks, but how it catches the light, fits your personal style, and even impacts the price.
In this guide, we’ll explore the 5 diamond cuts that continue to shine in popularity. Whether you’re shopping for an engagement ring, anniversary gift, or just dreaming of sparkle, understanding these shapes will help you choose the one that fits you best.
Let’s get to know these cuts, what makes them special, and which one might be your perfect match.
Why Cut Matters (A Lot More Than You Think)
When jewelers talk about “cut,” they’re not just referring to the shape of the diamond. It’s also about how the stone has been proportioned and faceted—basically, how well it reflects light.
According to the Gemological Institute of America (GIA), cut is the most critical of the 4 Cs (cut, color, clarity, carat) because it has the biggest impact on a diamond’s brilliance. A poorly cut diamond, even if it’s large and flawless, can look dull. Meanwhile, a well-cut diamond can sparkle like crazy—even at a smaller size.
Now, let’s break down the 5 diamond cuts that continue to steal the spotlight.
1. Round Brilliant Cut
The most popular and classic choice. In fact, over 60% of all diamonds sold are round brilliants.
- Shape: Perfectly circular
- Sparkle Factor: Maximum brilliance thanks to 58 well-placed facets
- Ideal For: Traditional styles, timeless looks, maximum sparkle
Round cuts are often pricier due to high demand and the amount of rough diamond lost in the cutting process—but they deliver on brilliance every time.
2. Princess Cut
Clean, modern, and edgy—literally.
- Shape: Square (or slightly rectangular) with pointed corners
- Sparkle Factor: Brilliant cut that rivals round diamonds in light reflection
- Ideal For: Contemporary styles, geometric aesthetics, budget-conscious buyers
Princess cuts give you a bold, structured look while still keeping the sparkle strong. They’re also more affordable per carat than rounds.
3. Cushion Cut
Think of this one as the vintage romantic of the group.
- Shape: Square or rectangular with soft, rounded corners (like a pillow)
- Sparkle Factor: Deep brilliance with a soft glow
- Ideal For: Vintage-inspired designs, softer and romantic aesthetics
Cushion cuts have been around for over a century, making them a top pick for those who love old-Hollywood glamour or antique-style rings.
4. Oval Cut
Elegant and elongating, the oval cut is quickly rising in popularity.
- Shape: Elongated version of the round cut
- Sparkle Factor: High brilliance with a slightly larger surface area
- Ideal For: Slender fingers, modern vintage lovers, those wanting a larger appearance
Oval diamonds tend to look larger than other cuts of the same carat weight, which makes them great value picks.
5. Emerald Cut
Minimalist and dramatic—this one is all about clarity and confidence.
- Shape: Rectangular with long, step-cut facets
- Sparkle Factor: Less “fire,” more “hall of mirrors” elegance
- Ideal For: Clean, bold styles, vintage looks, lovers of symmetry
Because the emerald cut highlights clarity over sparkle, it’s important to pick a high-quality diamond with minimal inclusions for this shape.
