Diamond Cuts Explained: What You Need to Know

Diamonds may be forever — but the way they’re cut can define how they shine, reflect light, and express your personal style. In this guide, we break down the different types of diamond cuts, what makes them unique, and how to choose the right one for your ring or custom piece.

What Are Diamond Cuts?

The diamond cut refers to how a diamond is shaped and faceted. This affects everything from its sparkle (brilliance) to its overall silhouette. Cut is one of the 4Cs of diamond grading (alongside color, clarity, and carat), and arguably the most important when it comes to beauty.

The Most Popular Types of Diamond Cuts

Below are the most commonly known diamond cuts and shapes, each with its own distinct style:

1. Round Brilliant Cut

The most classic and popular of all diamond cuts. It features 58 facets and maximizes brilliance.

2. Princess Cut

A modern square-shaped cut with sharp corners and brilliant faceting. Ideal for clean, contemporary rings.

3. Cushion Cut

A soft square with rounded corners, often described as romantic and vintage-inspired.

4. Oval Cut

Elegant and elongated, this cut enhances finger length and offers great brilliance.

5. Emerald Cut

Known for its clean lines and step-cut facets, the emerald cut emphasizes clarity over sparkle.

6. Radiant Cut

Combines the brilliance of round cuts with the shape of emerald or princess cuts.

7. Marquise Cut

A dramatic, tapered shape designed to maximize size appearance and elegance.

8. Pear Cut

Also known as teardrop-shaped, this unique style is bold and expressive.

9. Asscher Cut

A vintage step-cut similar to emerald, but square. Often associated with Art Deco designs.

10. Heart Cut

The ultimate symbol of romance. A technically challenging yet charming shape.

Rare and Unique Diamond Cuts

If you’re seeking something less traditional, consider unique diamond cuts like:

• Rose Cut – A vintage style with a flat base and domed top.
• Hexagon Cut – Geometric and edgy, perfect for modern custom designs.
• Trillion Cut – A triangular cut with lots of brilliance, often used as side stones.
• Old European Cut – A hand-cut antique shape popular in early 20th century rings.

These rare diamond cuts can add historic charm or avant-garde flair to your jewelry.
