Top 10 Most Popular Diamond Shapes of 2024

Happy New Year! As we step into 2024, the world of engagement rings continues to evolve with a harmonious blend of timeless classics and modern allure. If you're on the journey to find the perfect symbol of everlasting love, understanding the difference of diamond shapes is essential.

In this guide, we delve into the most popular diamond engagement ring shapes for 2024, ensuring your choice reflects both sophistication and uniqueness.

1. Round Brilliant Diamond Cut

Undoubtedly, the round brilliant diamond reigns supreme in 2024. Renowned for its unparalleled sparkle, this classic shape boasts an ideal cut with precisely 57 to 58 facets, making it the least wasteful and maximizing the diamond's brilliance.

Round brilliant cut diamonds are the most popular diamond shape  because of their perfect circular shape and the exceptional fire and brilliance that the facets create. They are also versatile and can hide imperfections. 
 
A facet is a flat surface on a diamond's geometric shape. Facets are cut into the diamond and arranged in a geometrical pattern.

Here are some guidelines for buying a Round Brilliant Cut Diamond:  

• Proportions: Some recommend a depth percentage between 59–61.8%, a table diameter between 53–58%, a crown angle between 34.3–35 degrees, and a pavilion angle between 40.6–40.9 degrees. Others recommend a depth percentage between 61.0% to 62.5%, a table size between 54.0% to 57.0%, and crown angles between 34.0° to 35.0°.
• Cut quality: A standard round excellent cut will be as brilliant without paying for the marketing. You can also look for a GIA certified diamond.
• Color: Round diamonds refract light better than any shape, so you can drop down to I or even J color.
• Inclusions: If the diamond has eye-visible inclusions, their size, location, and color are important factors in the overall beauty of the stone.
• Cut quality: Make sure the diamond is not too shallow or deep, as misalignment in diamond proportions causes a stone to lose its fire and brilliance.

Facets allow diamonds to absorb and reflect light. When cut by an expert, facets can cause optical effects on the surface of the diamond, and additional sparkle as they interact with light and each other. 

2. Princess Cut Diamond 

For those seeking a modern touch with a hint of royalty, the princess cut is the perfect choice. With its square or rectangular shape and pointed corners, this cut exudes contemporary glamor. 

A popular pick for engagement rings, the princess cut effortlessly combines tradition and quality, making it a timeless and fit choice.

Princess cut diamonds typically have 50–58 facets, but the most common pattern is 57. 

• 21 facets: On the crown
• 33 facets: On the pavilion
• 4 facets: On the girdle

Here are some guidelines for buying a Princess Cut Diamond:  

• Shape: A square princess cut should have a length-to-width ratio of 1.00 to 1.04 or less. A rectangular princess cut should have a ratio of 1.07 to 1.15. 
• Depth: A princess cut should have a depth of 69% to 76%. A depth and table of less than 75% can help maximize brilliance. 
• Table: A princess cut's table percentage is the width of the table divided by the width of the diamond. The most popular table percentages are 64% to 65%.
• Polish and symmetry: Look for an ideal cut grade with excellent symmetry and polish. These qualities can make a princess diamond more brilliant, fiery, and sparkly. 
• Color: Focus on I+ for color. You can usually find a good value with an eye-clean VS2 or SI1 clarity diamond. 
• Setting: Always set a princess cut diamond with prongs to protect the four corners. If the corners aren't protected, the diamond could chip if the ring gets caught. 
• Scintillation: A balanced contrast of light and dark patterns in the table and facets is important.  

Princess cut diamonds have a unique chevron pattern that gives them their distinctive look and brilliance. The facets contribute to the diamond's brilliance and sparkle. 

3. Oval Cut Diamond

The oval cut, characterized by its elongated round shape, is gaining popularity in 2024. This unique cut offers a distinctive and elegant look, creating an illusion of longer, slender fingers. An oval engagement ring is a testament to refined taste and a celebration of individuality.

 
Oval cut diamonds typically have 58 facets, including the culet, which is similar to the number of facets in a round diamond. 


Here are some guidelines for buying a Oval Cut Diamond:  

• Length-to-width ratio: The ideal ratio is 1.35–1.50, with 1.50 appearing larger. A lower ratio makes the oval plumper, while a higher ratio makes it skinnier. However, some prefer a skinnier oval, while others prefer a wider oval.
• Depth, table, and girdle: The ideal proportions are 57–63% depth, 53–63% table, and thin to thick girdle.
• Polish and symmetry: The polish should be excellent, and the symmetry should be excellent.
• Fluorescence: Fluorescence should not be present.
• Bow tie: Most shoppers want to avoid oval diamonds with pronounced bow ties. While it's possible to cut ovals in a way that minimizes or eliminates the bow tie, most ovals show this effect to some degree.
• Color: Up to H color is acceptable.
• Clarity: You can get away with up to SI1 due to the cut hiding flaws.

The oval cut is a rounded shape, with a ratio of 1.33 to 1.66. It's a good choice for those who want the sparkle of a round brilliant cut in a more elongated form.

4. Emerald Cut Diamond

For those who appreciate clarity and sophistication, the emerald cut remains a long time favorite. With its rectangular shape and cut corners, this diamond shape emphasizes clarity and elegance. An emerald cut engagement ring is a symbol of timeless beauty, making it a captivating choice for 2024.

Emerald cut diamonds have a simple geometry and less fire than brilliant or princess cuts. The light reflects off the facets in a unique way, creating a dramatic flashing effect. The large, open facets make it easier to see the body color of an emerald cut diamond, especially over 1.50 carats.


Here are some guidelines for buying a Emerald Cut Diamond:  

• Depth: A depth of 60–65% is recommended. The diamond's depth percentage affects how much light it reflects.
• Table: A table percentage of 60–65% is recommended because it opens up the stone and creates a "hall of mirrors" effect.
• Length to width ratio: The length to width ratio of an emerald cut diamond is usually between 1.30 and 1.50. A ratio of 1.40 is considered ideal, but ratios are dependent on personal preference. A lower ratio should be chosen for a more square shape, while a higher ratio is best for an elongated, more rectangular shape. Ritani's gemologists recommend a ratio of 1.45 to 1.55, but some people prefer longer, thinner cuts (around 1.6), and some prefer the shorter, squarer cuts (around 1.3).
• Polish/symmetry: Very good or excellent polish/symmetry is recommended.

Emerald cut diamonds are usually rectangular, but they can also be square. To add stability and prevent fractures, the corners of an emerald cut diamond are usually cropped.

5. Cushion Cut

With its square or rectangular shape and rounded corners, the cushion cut is a harmonious blend of softness and romance. This cut exudes a timeless charm, making it an ideal choice for those who seek a touch of vintage allure. A cushion cut engagement ring is a celebration of love in its purest form.



Cushion cut diamonds boasting 58 facets exude the timeless charm of the traditional "chunky" cushion cut aesthetic. On the other hand, when adorned with additional facets meticulously arranged in double rows, these diamonds take on a captivating allure known as the "crushed ice" look.


Here are some guidelines for buying a Emerald Cut Diamond:  

Depth and table: A general guideline is to have a depth and table under 70%. Cushion cuts are known for their deep proportions, so try to get under 67%.
Color: Cushion cuts retain color better than other shapes, so look for an H color or better when the diamond is set in platinum, white gold, or silver.
Polish and symmetry: Look for a diamond with very good or excellent polish and symmetry.
Length to width ratio: The length to width ratio should be within a range of 1.00 to 1.20.
Shape: Cushion cut diamonds can range from nearly round to nearly square. Look for one that's an attractive middle ground, with rounded corners and slightly curved sides.
Overall appearance: The overall appearance of the diamond is important.
Style: Determine the style or "flavor" that appeals most to your personal aesthetic.
Size, color, and clarity: Find a size, color, and clarity combination that fits your budget.

Some prefer a cushion cut diamond that is either square (a length to width ratio of 1.00 - 1.05) or slightly rectangular (1.10 - 1.20). A four-prong setting is best for a cushion cut diamond ring because it protects the gem without blocking light. For more rectangular cushions, a six-prong or double-prong setting can be used.  

6. Marquise Cut

For those desiring a unique and elongating effect on the finger, the marquise cut is a standout choice. Its elongated, pointed oval shape adds a touch of sophistication and uniqueness to the engagement ring. A marquise cut diamond is not just a statement piece; it's a reflection of your distinctive style.

Marquise cut diamonds are typically cut with 58 facets, with 33 on the crown and 25 on the pavilion. The pavilion facets can range from 4 to 8.  


Here are some guidelines for buying a marquise cut diamond:

• Length-to-width ratio: Marquise diamonds are typically cut with a ratio of 1.85–2.00, with about twice the length as the width. A lower ratio is better for a wider shape, while a higher ratio is better for a narrower, elongated shape. A ratio of 2:1 is considered "just right". Anything below 1.8:1 may look chubby, and anything over 2.2:1 may look starved.
• Bow-tie effect: Marquise diamonds often have some degree of a bow-tie, which can be light gray to black. The darker and wider the bow-tie, the more it can negatively affect the diamond's appearance. Marquise diamonds without a bow-tie may lack brightness and tend to be dull.
• Color: Marquise diamonds have a brilliant look and will exhibit a yellow tint. It's not recommended to choose a diamond with a color lower than G.
• Clarity: For the best clarity and value, look for an S1 or S2.
• Other factors: The diamond should have symmetrical proportions, a depth of 58–64%, and a table of 55–62%. The polish and symmetry should be very good or excellent, and the diamond should have a clarity of SI1 or better. Marquise diamonds often have some degree of a bow-tie, which can be light gray to black. The darker and wider the bow-tie, the more it can negatively affect the diamond's appearance. Marquise diamonds without a bow-tie may lack brightness and tend to be dull.

Marquise cut diamonds are an elongated oval with pointed ends and curved sides known as wings. The shape is said to resemble the hull of a small boat, which is why it's also called the "Navette" shape.

7. Pear Shaped

• Size: Pear shaped rings can range in size from very small to very large, so it's important to choose a size that complements the wearer's hand and style.
• Cut: The cut of the pear can have a big impact on the overall look of the ring. Some popular cuts include brilliant, oval, and marquise.
• Clarity: Pear shaped engagement rings are often made with diamonds, so it's important to choose a diamond with a high clarity rating.
• Setting: The setting of the pear can also make a big difference in the overall look of the ring. Some popular settings include solitaire, halo, and three-stone.

Due to the unique and unmistakable shape of the cut itself, pear-shaped engagement rings are said to symbolize empowerment, individuality and independence.

8. Asscher Cut

In 2024, vintage-inspired choices are making a comeback, and the Asscher cut is leading the way. Similar to the emerald cut but square, with larger step facets, the Asscher cut exudes vintage glamor with a modern twist. An engagement ring with an Asscher cut diamond is a timeless masterpiece, capturing the essence of bygone eras.





Here are some guidelines for buying a Asscher cut diamond:

• Consider the size of the ring: Asscher cut diamonds are typically larger than other cuts, so you'll need to make sure that the ring is the right size for your finger. A good rule of thumb is to choose a ring that is 1.5 to 2 times the width of your finger.
• Choose a quality diamond: When buying an Asscher cut diamond, it's important to choose a high quality stone. Look for a diamond with a clarity of VS1 or better and a color of G or better.
• Set the diamond in a durable setting: Asscher cut diamonds are relatively durable, but they can still be chipped or cracked if they are not set in a durable setting. Choose a setting that is made of a strong metal, such as platinum or gold.
• Consider your budget: Asscher cut engagement rings can range in price from a few thousand dollars to tens of thousands of dollars. Set a budget before you start shopping so that you don't overspend.

In 2001, brothers Edward and Joop Asscher, designed and patented the Royal Asscher Cut, which has 74 facets compared to the original Asscher cut's 58 facets.

• Clarity: A clarity range of SI2 or above is recommended.
• Cut: The corners should be evenly truncated and avoid outlines with overly truncated corners. The diamond should have a centered culet and parallel sides. Avoid corners that are uneven, either too wide, or too narrow.

• Dimensions: A good length to width ratio is attractive. The diamond's dimensions, such as length, width, and depth in millimeters, are more accurate than its carat weight.

• Cut specifications: A table percentage of 54–60%, a depth of 59–63%, a crown angle of 14–15.5, and a pavilion angle of 40.5–43 can help the diamond sparkle.
• Ratio: The length to width ratio should be between 0.90 and 1.10 to make the heart as tall as it is wide.

• Quality: Look for diamonds with a very good or excellent polish/symmetry, a color of G or better, and a clarity of SI1 or better.
• Girdle: A very thin to slightly thick girdle is best, and if the girdle is extremely thick or thin, it shouldn't be considered.
• Size: To make the heart shape as visible as possible, it's best to choose a diamond of 1 carat or larger.
