What Makes a Diamond Cut "Popular" in 2026?
We may begin with the basics. A diamond's cut is the shape and faceting of the stone. It covers not just the outline (round, oval, and so on) but how the stone handles light. In 2026, it is not only about sparkle, though sparkle still matters most. It is also about self-expression and individuality.
Five factors shape which diamond cuts trend this year:
-
Celebrity proposals
-
Social media celebrities and Pinterest boards (needless to say)
-
Growing interest in lab-grown diamonds
-
The retro chic makes a comeback
-
High-tech precision cutting

Oval Diamonds - Still the Reigning Queen
The Reason Why Oval Diamond Trend Is Here to Stay

Celebrity Influence
Celebrities such as Kourtney Kardashian and Hailey Bieber have kept the oval cut in view. More couples are choosing it as their first pick.
Princess Cut Popularity Is Making a Huge Comeback
The princess cut suits the buyer who wants sparkle without a traditional round stone. Its square outline reads as sharp and modern, and it works well in minimalist settings.
What's New for 2026?
Think clean lines, east-west settings, and custom stacks. Personalized, edgy princess cut engagement rings are the in-thing of the year.
Cushion Cut Engagement Rings - Soft, Romantic & So 2026
There is something warm and comfortable about a cushion cut. Its shape is pillow-like with rounded corners, which makes it vintage and timeless at the same time.
Vintage-Inspired Diamond Cuts Are Back
The vintage-inspired look for 2026 pairs cushion cuts with rose gold or milgrain detailing.
Emerald Cuts - Sleek and Sophisticated
Emerald cuts reward clarity, so the stone itself has to be clean.

If you like clean lines and a bit of drama, look at emerald cuts. Their mirrored effect is simply subdued glam.
A Draw for the Confident Buyer
The long, open facets of an emerald cut hide very little, so clarity matters more in this shape.
Radiant Cut - The Sparkle Queen
The radiant cut combines the brilliance of a round with the outline of an emerald cut. It is bold, lively, and full of movement.
Why These Designs Are Trending in 2026
Look for these cuts in mixed-metal settings, halos, and three-stone rings. They turn up in every 2026 diamond jewelry round-up.
Pear-Shaped Diamonds - Elegant With an Edge
With its teardrop outline and smooth curves, the pear cut appeals to buyers who want something less common.
Top Diamond Cut for the Bold
This asymmetrical look is what brings some pizazz to solitaires as well as cluster rings. And indeed, it even looks fantastic in selfies.
The Rise of Antique & Vintage-Inspired Cuts
Enter the Portuguese Cut
The Portuguese cut is having a revival. Its antique look suits buyers who want a cut with real history behind it.
Why It's Trending in 2026
People are more and more interested in unique rings and the Portuguese cut delivers an antique, heirloom look with a modern finish, especially in lab-grown stones.
Marquise Cut - The Underrated Star
Marquise cuts are long, sharp and dramatic and yes, make a finger look long.
The Comeback Cut of the Year
They were written off as dated, but new settings and bolder styling have made them a cut to watch in 2026.
Asscher Cut - Retro and Regal
The Asscher cut is square and step-faceted, with a clear Art Deco character.
For Lovers of Symmetry
This is all about lovers of clean geometry. Pair it with a cathedral setting for old-world glamour.
Heart-Shaped Diamonds - Quirky Meets Romantic
The Most Sentimental of All Diamond Shapes
Heart-shaped diamonds may not be to everybody, but they are ideal to romantic personalities, and they are turning up more often in celebrity engagement rings.
