Diamond Shapes

One of the most exciting parts of choosing a diamond is deciding on its shape. Whether you’re drawn to the timeless beauty of a round diamond or the modern allure of a pear-shaped stone, the shape you choose can say a lot about your style and personality. Let’s explore the most popular diamond shapes, their unique features, and which might be the best fit for you.

Round Brilliant: The Classic Choice

Round brilliant diamonds are by far the most popular—and for a good reason. This shape is all about maximum sparkle. With 58 expertly cut facets, round diamonds reflect light better than any other shape, making them the go-to choice for those seeking brilliance. If you want something timeless and classic that’s guaranteed to turn heads, you can’t go wrong with a round diamond.

Why Choose Round: Classic, versatile, and full of fire. It suits nearly every ring setting and finger shape.

Helpful Tip: Because of their popularity, round diamonds often carry a higher price per carat than other shapes. Prioritize cut quality to get the most brilliance for your budget.

Princess Cut: Modern Elegance

The princess cut is the most popular fancy shape, offering a beautiful mix of contemporary style and eye-catching sparkle. With its sharp, square edges and distinctive brilliance, the princess cut is perfect for someone who wants a modern twist on tradition. This shape looks stunning in almost any setting, from simple solitaires to elaborate halos.

Why Choose Princess: It combines sparkle with a sleek, modern silhouette. The square shape is great for those who love symmetry and clean lines.

Helpful Tip: Be mindful of the corners. Princess-cut diamonds can be more prone to chipping if the corners aren’t protected by prongs or a bezel setting.

Cushion Cut: Vintage Charm

For a diamond with a soft, romantic look, the cushion cut may be your perfect match. With rounded corners and larger facets, this shape has an antique feel that’s loved for its charm and character. Cushion-cut diamonds often have a softer sparkle, making them a great choice if you’re drawn to vintage or classic designs.

Why Choose Cushion: Ideal for someone who loves vintage-inspired styles. Its pillow-like shape adds a romantic, softer feel to your ring.

Helpful Tip: Cushion cuts come in square or rectangular proportions. Decide which suits your style best before making your choice.



Oval: Sleek and Elegant

Oval diamonds offer the brilliance of a round shape but in a more elongated form. The oval shape can also make the diamond appear larger than it is, while the elongated design has a slimming effect on the finger. This is a great choice for someone who wants something unique but still appreciates the sparkle of a round diamond.

Why Choose Oval: It offers the same brilliance as a round diamond but with a more modern twist. The elongated shape can make fingers appear longer and slimmer.

Helpful Tip: Look out for the “bow-tie” effect—a shadow across the center of the diamond that’s common in oval shapes. A well-cut oval will minimize this effect.



Emerald Cut: Understated Glamour

If you’re looking for elegance with a touch of old Hollywood glamour, the emerald cut is for you. Its long, clean lines create a “hall of mirrors” effect that’s subtle but captivating. Emerald cuts don’t sparkle in the same way that round or princess cuts do, but they have a unique clarity that showcases the stone’s depth and clarity.

Why Choose Emerald: Understated yet striking, it exudes elegance. It’s perfect for those who appreciate a more refined, sophisticated look.

Helpful Tip: Because the emerald cut’s facets are larger, inclusions and color can be more visible. Opt for higher clarity and color grades when choosing this shape.




Marquise: Bold and Dramatic

The marquise cut is one of the most distinctive shapes, known for its elongated body and pointed ends. This diamond shape has a regal air and makes the stone look larger than its carat weight suggests. The marquise also has the effect of elongating the finger, creating a bold and elegant look.

Why Choose Marquise: Its unique shape makes a statement. It’s great for someone who wants to stand out with a bold, dramatic look.

Helpful Tip: Like ovals, marquise cuts can suffer from the bow-tie effect. Make sure to inspect the diamond for this before purchasing.

Pear: Unique and Romantic

Pear-shaped diamonds, also known as teardrop diamonds, are a blend of the round and marquise shapes. This unique hybrid has a rounded end that tapers to a point, creating a distinctive and romantic silhouette. The pear shape can make the stone appear larger and works well in a variety of settings.

Why Choose Pear: It’s a perfect blend of uniqueness and romance. This shape can look flattering on the hand while offering a little extra sparkle.

Helpful Tip: Always check that the point is properly protected with a prong to avoid damage.

Asscher Cut: Vintage with a Modern Twist

Similar to the emerald cut, the Asscher cut has a square shape with step-like facets that create a stunning “hall of mirrors” effect. This shape, known for its deep pavilion, was popular during the Art Deco period and has a vintage appeal that’s been modernized in today’s jewelry.

Why Choose Asscher: For the vintage lover who appreciates bold lines and symmetry. Its unique cut is eye-catching but elegant.

Helpful Tip: Like the emerald cut, the Asscher showcases the diamond’s clarity, so higher clarity grades are recommended.

Choosing the Right Shape for You

Choosing a diamond shape is all about personal preference. Ask yourself what feels right: Do you want something timeless or trendy? Classic or bold? The shape you choose will reflect your personal style, so take your time, explore different options, and go with what speaks to you the most.
