Diamond Cut Guide: The Most Popular Engagement Ring Styles

When choosing a diamond, few factors influence its beauty more than the diamond cut. Cut refers not only to the shape of the stone but also how well it has been proportioned, polished, and faceted to reflect light. A diamond’s sparkle—commonly called brilliance—comes directly from its cut. For couples searching for the best diamond cut for an engagement ring, understanding the differences between cuts is essential. This diamond cut guide explores the most popular shapes, their symbolism, and what makes each unique.

Round Brilliant Cut

The round brilliant cut is the most classic and timeless choice. Designed with 58 facets, this cut maximizes brilliance and fire, making it the most sparkling of all diamonds. Its popularity stems from versatility—it suits modern, vintage, or minimalist ring settings.

Princess Cut

The princess cut offers a modern square shape with pointed corners. Known for its sharp, clean lines, it combines brilliance with a contemporary flair. It is the second most popular cut after the round, often chosen by those who love geometric beauty.

Cushion Cut

With soft, rounded edges resembling a pillow, the cushion cut has a romantic, vintage feel. Once the most common cut in the 19th century, it has made a comeback in modern jewelry.

Oval Cut

The oval cut elongates the finger while delivering brilliance similar to a round diamond. It’s perfect for those who want the shine of a round cut but with a more distinctive shape.

Emerald Cut

The emerald cut stands out for its rectangular shape and step-cut facets. Rather than brilliance, it emphasizes clarity and depth, producing a “hall of mirrors” effect. This sophisticated cut appeals to buyers who appreciate elegance over flash.

Marquise Cut

Shaped like a boat or eye, the marquise cut has pointed ends that create a dramatic, elongated look. Legend says King Louis XV of France commissioned this shape to resemble his mistress’s smile.

Pear Cut

Also known as the teardrop cut, the pear cut combines the brilliance of a round with the elegance of a marquise. One rounded end and one pointed end create a unique silhouette.

Asscher Cut

Similar to an emerald cut but square in shape, the Asscher cut was developed in the early 20th century. With step-cut facets and a deep pavilion, it creates a mesmerizing geometric pattern.

Radiant Cut

The radiant cut blends the brilliance of round and princess cuts with a rectangular outline. Its many facets produce intense sparkle, making it ideal for those who want the fire of a brilliant cut but prefer a less common shape.

Choosing the Best Cut for You

When selecting the best diamond cut for an engagement ring, consider personal style, lifestyle, and budget. A round brilliant might be the go-to for classic sparkle, while an emerald cut appeals to lovers of elegance. Oval and cushion cuts provide a blend of brilliance and distinctiveness, while marquise or pear cuts create bold statements.
