Today, there is an abundance of different diamond shapes to choose from, and each shape has its own unique style and brilliance. Deciding on diamond shape is one of the most important factors of shopping for engagement rings or other pieces of fine jewelry. Your stone is the star of the show, and it needs to be everything you’ve dreamed of. Learn the pros and cons of each diamond shape to determine which one is right for you and guide you on the path of choosing a diamond.



What is Diamond Shape?

Diamond shape refers to the silhouette or general look of a stone. There are many different shapes available in the market today, but there are 11 shapes that are purchased most frequently. An important fact to note is that all shapes that are not a Round Brilliant are referred to as fancy shape diamonds. Each shape differs not only in physical form, but in light return as well. How much sparkle a stone emits is correlated with how many facets it has and their general pattern. While a Round Brilliant shape will emit the most amount of light return because of its ideal facet pattern, shapes like Emerald and Asscher, which are step cuts, will not have as much sparkle but are appealing because of their unique style.

The 11 most popular stone shapes.

Purchasing a diamond or simulated lab grown diamond whether for a piece of fine jewelry or an engagement ring- is an important decision. It can sometimes be a big financial decision as well, which is why it’s so important to learn about diamond quality and how to choose the perfect stone. To figure out which diamond shape is right for you, first make sure that you are thoroughly acquainted with the most popular ones.



Diamond Shape vs. Diamond Cut

Before learning about each shape, it’s important to differentiate diamond shape from cut. Diamond shape and diamond cut are often confused when choosing a diamond or diamond simulant. The cut of a diamond does not refer to the shape of the stone, but actually refers to how well a diamond’s facets interact with light. Cut is determined by measuring brightness, fire and scintillation. All three of these components have to do with the amount of sparkle the stone emits and how well it emits it. The closer a stone is to an Ideal Cut, the more sparkle it will emit and the more valuable it becomes.



Different Diamond Shapes

Narrow down your engagement ring search by choosing the perfect diamond shape. Of the 11 most popular shapes, each one looks and wears differently. To better determine which shape is right for you, learn the most important facts about each one.

An Asscher Nexus Diamond alternative.

Asscher
An Asscher diamond is considered a fancy shape (as are all shapes outside of a Round Brilliant). It’s very unique compared to other shapes in that it somewhat resembles the silhouette of a Princess stone but instead is considered a step cut. A step cut is a type of stone that has large, open facets that look like a staircase when viewed up close. Unlike a brilliant cut, it shows long flashes of sparkle. Asscher stones are sometimes referred to as a square Emerald shape, as they both feature 58 facets.

A Cushion Nexus Diamond alternative.

Cushion
A Cushion diamond resembles a pillow because of its rounded edges. It is a cross between a Round Brilliant and a Princess- the two most classic shapes- making it a perfect choice for those who are looking for classic style with a modern twist. Although the exact number can differ, the average Cushion cut diamond or diamond simulant has around 58 facets. This gives it a similar appearance and light return pattern as a Round Brilliant, which could be one of the main reasons it is such a popular shape.

An Emerald Nexus Diamond alternative.

Emerald
The Emerald shape is often used in vintage designs as it was such a popular style during the Art-Deco movement in the 1920s. It is a rectangle that features slightly cropped edges and long open facets that make a captivating step-cut design. When looked at up close, you can see a dazzling hall-of-mirrors effect. Depending on the style you want, an Emerald shape can be cut to look more square or elongated and rectangular in shape. While this shape is unique and utterly captivating, keep in mind that since there are fewer facets featured on the table, inclusions are much more easily seen if you choose a traditional diamond.

A Heart Nexus Diamond alternative.

Heart
Of all diamond shapes, the Heart cut is by far the most romantic. It symbolizes true love and femininity. This shape is usually designed as a solitaire, as it is so striking on its own. Heart cut diamonds usually feature around 58 facets, although their pavilion may feature anywhere from 6 to 8 facets. Traditional diamonds featured in this shape sometimes have a bow-tie effect, where it looks as though there is a dark spot in the stone because of a shadow being cast from the central facets. This is much less likely to occur with an Ideal Cut diamond or diamond simulant such as the Nexus Diamond™ alternative.

A Marquise Nexus Diamond alternative.

Marquise

Elongated and uniquely modern, the Marquise shape is growing in popularity. It’s much different than all other shapes as it comes to two points at both ends. There are many reasons women choose a Marquise cut diamond, but the two most common are because it gives the appearance of a more slender finger along with appearing larger than it actually is. So a one carat Marquise stone will appear larger than a one carat Round Brilliant because of its length.

An Oval Nexus Diamond alternative.

Oval
An Oval shape resembles the simplicity of a Round Brilliant, but is elongated to create a more modern style. It is extremely popular, not only for its versatility, but because it tends to appear larger. Like other elongated shapes such as Pear and Marquise, Oval will have a slenderizing effect on your finger when set in an engagement ring. It is also a great choice for a solitaire design because it enhances the ring’s uniqueness, unlike a more traditional style.

A Pear Nexus Diamond alternative.

Pear
Pear shapes also feature an elongated design that flatters the finger and appears larger. Although some choose to wear it differently, it’s traditionally worn pointing away from your hand when featured in an engagement ring. This lends the length throughout your finger. Pear shaped diamonds and diamond simulants are extremely modern, which is why the shape is commonly paired with modern setting styles. Halo engagement rings look luminous with a unique shape like Pear.

A Princess Nexus Diamond alternative.

Princess
Princess cut diamonds are the second most popular stone shape following Round Brilliant cut diamonds. There are a couple of different reasons for this, but the most important is that it has the second closest facet pattern to Ideal. This means it shows more sparkle than most other cuts. It is also extremely popular for its classic square shape, which is extremely versatile and timeless enough to be in style for years to come. If you’re looking for maximum sparkle, but want something that stands out more than a classic Round Brilliant, a Princess cut diamond or diamond simulant may be the perfect choice for your engagement ring or next piece of fine jewelry.

A Radiant Nexus Diamond alternative.

Radiant
As the name suggests, this shape is extremely sparkly. A Radiant shape has the appearance of a rectangle but its facet pattern is much different than an Emerald. It features a shocking 70 facets, which is much higher than most other shapes. This gives it all-over sparkle, much like a Round Brilliant, but even more captivating. Due to its many facets, it’s important to choose an Ideal or Very Good cut when purchasing a traditional diamond as inclusions will be easier to spot.

A Round Brilliant Nexus Diamond alternative.

Round Brilliant
Round diamonds are the most popular of all stone shapes. As the name suggests, this cut appears as a perfect circle. They are so popular that more than half of all diamonds sold are cut into a Round Brilliant shape. This is because they feature an Ideal facet pattern which results in the maximum amount of light return. That means more sparkle for your buck. Plus, the shape in itself is classic enough to pair well with any setting or detail you choose. A Round Brilliant stone is an excellent choice for anyone looking for a timeless piece that has exquisite brilliance and fire.

A Trillion Nexus Diamond alternative.

Trillion
Although the Trillion looks like a triangle in shape, it features rounded corners which give it a unique look. This shape is striking as side stones, but is not commonly featured as a center stone. Due to this, Trillion shapes are more popular in fine jewelry. Since the Trillion shape is asymmetrical, it is designed with special prongs- like a martini setting- to fit properly. Keep in mind, because this shape comes to three points it is more prone to chipping. This is why you’ll want to make sure you choose a secure setting if you end up choosing a Trillion shape.



The Meaning Behind Different Diamond Shapes

Many consumers wonder, “what do different diamond shapes mean?” While some shapes are said to have symbolism, it’s more important to consider what different diamond shapes mean to you and your significant other. Whether it’s a story of your history or a brief look into the future, a shape can hold unique meaning in your heart forever.

Some suggest that the traditional Round Brilliant shape is perfect for a woman who has classic taste. She may be allured by timeless adornments hoping to pass them down to the next generation, or enthralled by repetitive patterns. It may even suggest everlasting love, destined to go on forever with no end in sight as a circle suggests. Opposingly, an Emerald shape is said to allude to the dazzle of the 1920s: bright, flashy and new. Perhaps you want your relationship to always feel unique and fresh, just like a step-cut suggests.



Choosing Diamond Shape
