A Guide to Lab-Grown Diamond Shapes: Find Your Perfect Match
The shape of a diamond is one of the most personal choices you'll make when selecting jewelry. It’s not just about style—it’s about what speaks to you. From the timeless appeal of a round brilliant to the architectural lines of an emerald cut, each shape carries its own character and charm.
Here, we break down the most sought-after lab-grown diamond shapes to help you find the one that truly reflects your taste.
Round Brilliant Cut
The round brilliant remains the most popular choice for engagement rings, known for its exceptional sparkle. With 58 precisely angled facets, it’s crafted to maximize light return and brilliance. This shape works beautifully in almost any setting, from simple solitaires to detailed halo designs.

Princess Cut
A favorite for its modern elegance, the princess cut features sharp corners and a square shape. It offers brilliant faceting and a contemporary look that pairs well with both classic and more elaborate settings. Due to its pointed corners, a secure setting is recommended to protect the stone.

Cushion Cut
Sometimes called a “pillow cut,” the cushion diamond blends rounded corners with larger facets for a soft, romantic glow. It has a vintage feel that works especially well in halo or antique-inspired settings.

Oval Cut
Oval diamonds offer a unique twist on the classic round shape. Their elongated form can make the finger appear longer and slimmer. They carry plenty of sparkle and are increasingly chosen for their blend of tradition and individuality.

Emerald Cut
Recognizable by its stepped facets and open table, the emerald cut emphasizes clarity and elegance over intense sparkle. Its clean, geometric lines appeal to those who appreciate understated sophistication.

Radiant Cut
The radiant cut combines the brilliance of a round diamond with the defined shape of an emerald cut. With trimmed corners and plenty of sparkle, it’s versatile and eye-catching—ideal for those who want both shape and shine.

Pear Cut
A hybrid of the round and marquise shapes, the pear cut (or teardrop) is elegant and distinctive. It looks particularly striking set with the point facing upward or outward, adding a touch of graceful elongation.

Marquise Cut
With pointed ends and an elongated form, the marquise cut is dramatic and historic. It’s known for making the diamond appear larger than its carat weight and pairs well with vintage-inspired settings.

Heart Cut
The heart-shaped diamond is a bold symbol of romance. It requires skilled cutting to achieve symmetry and balance. Often chosen for sentimental jewelry such as promise rings or anniversary pieces.

Asscher Cut
Similar to the emerald cut but square, the Asscher cut has a deep pavilion and cropped corners, giving it a strong Art Deco vibe. It’s a statement shape for those who love vintage glamour and geometric precision.
