What Are Different Types of Diamond Shapes?

VRAI | May 3, 2021

Diamond shapes refer to the diamond’s physical form and are usually the most distinguishable feature. A diamond’s shape is considered its personality and symbols of self-expression.

Below is a guide to ten different diamond shapes for engagement rings. For fine jewelry, choose from fifteen diamond shapes, including eight Iconic Shapes — uniquely shaped lab-grown diamonds that are an unprecedented expression of craftsmanship highlighted by an inventive prong placement.

Read on to discover our ultimate guide to engagement ring and fine jewelry VRAI created diamond shapes, from A to Z.

What is the difference between a diamond shape and a diamond cut?

A diamond shape refers to its exterior form and is recognizable even from a distance. Although often associated with cut (which refers to a diamond’s facets), the diamond shape more accurately represents the diamond’s overall look.

A diamond’s cut is better seen up close. Cut is all about facets — the flat surfaces on a diamond that allow light to enter and reflect back. The brilliant cut on a Round Brilliant shaped diamond allows for light to bounce back and shine in many different directions at once. The linear step cut of an Emerald shaped diamond creates what is referred to as a “hall of mirrors” effect.

What are top diamond shapes for engagement rings?

This list of ten features some of the most popular diamond shapes for engagement rings — which is why each is featured in VRAI’s engagement ring settings.

Along with their physical description, there is information on their cut, their number of facets, and which of the other 4Cscarat weight, clarity, and color — should be prioritized.

1. Round Brilliant shaped diamonds

A true classic and the perfect balance of proportion and symmetry, this rounded shape has sparkling facets that maximize brilliance and fire. The Round Brilliant is a timeless cut that stands the test of time and is the most popular of all diamond shapes.

It is also often considered one of the most expensive diamond shapes (but with VRAI’s vertical integration, you can buy a Round Brilliant cut diamond at a more accessible price point). The round brilliant’s poetic curves that come full circle to signify eternal love are highlighted in multiple VRAI engagement ring styles.

Shop Round Brilliant
  • Facets: 57, triangular and kite-shaped

  • Cut: Brilliant

  • Known for: Representing 75% of all diamonds sold, this diamond is the ultimate classic shape.

  • Prioritize: Cut. They are known for their much-desired brilliance, so compromise on carat size, color, or clarity before cut quality for maximum sparkle.

2. Oval shaped diamonds

This soft silhouette with its elongated shape is one of our most-loved. The Oval elongates the fingers, hides inclusions, and looks large with its generous surface area. Our oval cut engagement rings highlight the VRAI created diamond’s beautifully balanced curves.

Shop Oval

* Facets: 57, triangular and kite-shaped

  • Cut: Modified Brilliant

  • Known For: Having the same brilliance as a Round Brilliant, but with an elongated form.

  • Prioritize: Carat. The Oval maximizes carat weight because of its surface area.

  • VRAI’s ratio: 1.40 : 1.

3. Emerald shaped diamonds

One of the oldest diamond shapes and beloved for it’s clean, linear lines, the emerald cut is a testament to exacting precision. This rectangular shape features step-cut facets running down the sides to draw attention towards the center of the stone.

These long, symmetrical and narrow facets add depth and dimension, while drawing in light and spotlighting clarity, making this shape look modern and elegant. Crystalline and sleek, our emerald cut engagement rings highlight long, narrow facets for a sophisticated and stunning “hall of mirrors” effect.

Shop Emerald
  • Facets: 49, rectangular

  • Cut: Step

  • Known for: Being one of the oldest diamond shapes, a “hall of mirrors” effect

  • Prioritize: Clarity. The step-cut facets make a diamond’s natural inclusions more visible, so opt for VS1 or higher grades.

  • VRAI’s ratio: 1.45 : 1

4. Pear shaped diamonds

The Pear’s teardrop silhouette leads to a single point, balancing brilliant facets with a pleasing proportion and depth while elongating the fingers. Pear-shaped diamonds, once preferred for fine jewelry over engagement rings, have gained in popularity recently with their blend of round and marquise shapes and symbolic teardrop design. Tapered to perfection, our pear cut engagement rings highlight VRAI created diamonds with a balance of proportion and depth.

Shop Pear
  • Facets: 56, triangular and kite-shaped

  • Cut: Brilliant

  • Known for: Resembling a “tear of joy,” appearing larger than other diamond shapes of the same carat weight. It may possess a slight "bow-tie" effect in its center, which is the dark shadow that appears from the face-up. The degree of “bow-tie” severity varies so you can base your decision on personal preference.

  • Prioritize: Color, clarity or cut. Pear cut diamonds feature a large face and facets, so prioritize these 3Cs before carat size for maximum brilliance.

5. Radiant shaped diamonds

The perfect balance of beauty and strength, the Radiant combines the unmatched brilliance of the Round Brilliant with the distinct silhouette of the Emerald.

Admired for its impeccable symmetry and fiery appearance, this shape is an ideal center-stone for any of our customizable engagement ring settings. Composed of 70 brilliant cut facets, this unique cut offers ideal brilliance and elongation while the beveled corners add durability.

Shop Radiant

  • Cut: Brilliant

  • Known for: Unique cut and proportions, cropped corners that increase durability to chipping for those with an active lifestyle.

  • Prioritize: Cut. This shape features brilliant facets which hide inclusions and reflect light well, so cut comes before clarity, color, or carat weight here.

6. Cushion shaped diamonds

Called a “Cushion” for its pillow-like appearance, this soft square shape features rounded corners and a brilliant cut. Large facets highlight clarity, disguise inclusions and maximize radiance, creating the look of crushed ice when reflecting light.

Because of this, the cushion cut diamond is considered to be of the diamond shapes that shines the most vividly. This contemporary favorite is a balance between a classic round and uniform square and comes in a variety of VRAI engagement ring styles.

Shop Marquise
  • Facets: 56 triangular and kite-shaped

  • Prioritize: Color, clarity, or cut. A Marquise’s large face means that carat size should come last for maximum brilliance.

  • Our ratio: 1.85 : 1.

What diamond shape is best for you?

There is no such thing as the “best” diamond shape. When choosing a diamond shape for an engagement ring, personal preference and taste must come first. So instead of asking what the best diamond shape is, you should ask which shape is best for you.

The Round Brilliant is by far the most popular diamond shape in the world. And Oval shaped diamonds are the most sought-after VRAI created diamonds. When it comes to selecting your shape, consider your personal style.

Round Brilliant, Oval, and Emerald shapes are thought of as classic. Pear, Marquise, and Asscher shaped diamonds are considered vintage-inspired and romantic. Trillion and Radiant are considered to be modern-yet-timeless.

The best way to choose is to explore VRAI created diamonds and find the shapes that resonate with you the most.

Which diamond shape sparkles the most?

The Round Brilliant diamond “sparkles” the most. Sparkle actually refers to a diamond’s fire and scintillation. The rounded shape, and angled sides accentuate a Round Brilliant’s 57 facets. But not every Round Brilliant is guaranteed to shine bright — cut must be prioritized to ensure its brilliance.

After the Round Brilliant, Oval, Marquise, and Pear shaped diamonds are considered extremely brilliant. And then Cushion, Emerald, Asscher and Radiant shaped diamonds are categorized as brilliant.

What is the most expensive diamond shape?

Round brilliant shaped diamonds are the most expensive diamond shape. Their price is affected by their popularity. On average, between 50 to 75% of all the diamonds sold around the world are Round Brilliants. Because they are so popular, many retailers can charge more for this sought-after shape.

Which diamond shapes look the biggest?

Marquise, Pear, Oval, and Emerald shaped diamonds appear the largest. This is due to their elongated form. Even though a 1-carat Oval shaped diamond will weigh the exact same as a 1-carat Round Brilliant diamond, its large open face will make it appear bigger. These styles are perfect for those wanting to maximize the size of their engagement ring center stone.
