Diamond Shapes 101: A Complete Guide to Finding your Perfect Ring

Choosing an engagement ring is one of the most exciting decisions you'll make —but with so many unique shapes to choose from, how do you know which is right for you?

When you look at a ring, the first thing that catches your eye is the shimmer of the center stone—and it’s the same detail your friends and family will admire every time you show off your ring for years to come! This means it is important to choose a stone that speaks to you. Each shape offers unique characteristics, from brilliance and sparkle to size appearance and finger-flattering effects. This guide will break down the eight most popular diamond shapes, their pros and cons, and what you need to know before choosing your perfect ring.

Round: The Timeless Classic

The round diamond is the most popular and classic diamond shape, consisting of 58 facets that reflect light brilliantly. If you’re looking for maximum sparkle, a round is a cut for you. 

Pros:

• Timeless and never goes out of style
• Offers maximum brilliance and sparkle
• Hides inclusions well, so you can sacrifice clarity for a bigger stone
• Holds value over time

What to be aware of:

• Appears slightly smaller than other cuts of the same carat weight
• Due to high demand, round diamonds are typically more expensive than other shapes
  
  

Princess: The Bold & Modern Square

The princess cut is square or rectangular with pointed corners. It has a clean, angular look with intricate facets. It’s perfect for someone who loves a bold and contemporary look.

Pros:

• More affordable per carat compared to other cuts
• Offers great brilliance and fire for a modern aesthetic

What to be aware of:

• Princess cuts have declined in popularity in recent years
• The sharp corners can be more prone to chipping if not protected by a secure setting
  
  

Oval: Elegant and Finger-Flattering

Oval diamonds are a popular choice for those who want an elongated shape and a similar brilliance to the round diamond.

Pros:

• Appears larger than a round stone of the same carat weight
• Flattering on the hand

What to be aware of:

• Some ovals have a bow-tie effect, a dark shadow in the center of the stone (always check in different lighting!)

Marquise: The Dramatic Statement

The marquise diamond is an elongated shape with pointed ends, creating a dramatic and unique look. It is shaped similarly to a football. 

Pros:

• Maximizes size appearance due to its long, shallow cut
• Similar to oval cuts, it elongates the finger beautifully

What to be aware of:

• The ideal length-to-width ratio is around 2:1 for a balanced look
• Like oval and pear cuts, watch for the bow-tie effect
  
  

Emerald: The Sophisticated Stunner

The emerald cut is a rectangular shape with cut corners and a step-cut facet pattern. It has a sophisticated and elegant look. 

Pros:

• Timeless and sophisticated with a vintage charm
• Highlights clarity and color beautifully

What to be aware of:

• Does not sparkle as much as brilliant-cut diamonds
• Inclusions are more visible, so a higher clarity grade is recommended
  
  

Cushion: The Romantic Soft Square

The cushion cut is a square or rectangular shape with rounded corners and larger facets, giving it a soft, romantic
look.

Pros:

• Offers great brilliance while maintaining a romantic, antique feel
• More affordable per carat compared to round cuts

What to be aware of:

• The length-to-width ratio varies—some cushions are more square, while others are elongated (which has become trendier)!

Pear: The Unique Teardrop

The pear-shaped diamond is a teardrop-shaped diamond with one pointed end and one rounded end. It is a unique and elegant choice that has regained popularity in recent years.

Pros:

• Appears larger than round diamonds of the same carat weight
• Unique and stylish, perfect for those who want something different

What to be aware of:

• Some people prefer a "chubby" vs. elongated pear shape—it’s a personal preference!
• Like oval and marquise cuts, be mindful of the bow-tie effect

Asscher: The Vintage Art Deco Icon

The Asscher cut is similar to the emerald cut, but it is square and has larger step facets. It has a vintage, Art Deco feel that makes it a popular choice for those who love antique-style engagement rings.

Pros:

• Offers a beautiful, symmetrical "hall of mirrors" effect
• A great choice for vintage and Art Deco lovers

What to be aware of:

• Clarity is key—inclusions are easier to spot
• Has a smaller face-up appearance compared to other cuts of the same carat weight

Radiant: The Crushed-Ice Sparkler

The radiant cut is a rectangular shape with cut corners and a brilliant sparkle. It is a popular choice for those who want a modern-looking diamond that still has a classic appeal.

Radiants are often confused with cushion cuts. Unlike a cushion, radiant cuts have cut corners.

Pros: 

• Offers maximum sparkle for those who love brilliance
• More durable than princess cuts due to its trimmed corners

What to be aware of:

• Pairing radiants with side stones can be tricky—always check how they look together before committing

Which Diamond Shape is Right for You?

Your perfect diamond shape depends on your style, priorities, and budget. If you love timeless elegance, a round or emerald cut may be ideal. If you want maximum size appearance, consider oval, marquise, or pear cuts. If you're drawn to bold and modern designs, the radiant or princess cut may be your perfect match.

No matter which shape you choose, the most important thing is that it feels right for you and your partner!
