Everything You Wanted to Know About Diamond Shapes

While some may prioritize size or sparkle, there’s one element of diamonds that we think is completely underappreciated: diamond shape! With so many unique shapes to choose from, Shane Co. lets you express your individuality with the largest variety of traditional and fancy-shaped diamonds, rubies and sapphires.

What is shape?

All 9 shapes of diamonds.

The “shape” of a diamond or other precious stone is the outline of the stone, looking at it from the top down. We typically think of 10 diamond shapes — round, cushion, princess, emerald, asscher, marquise, heart, oval, pear and radiant. Each shape is carefully cut by expert diamond cutters to obtain maximum sparkle and create a specific style. Let’s take a closer look at each of our favorite diamond shapes.


Round diamond.

Round diamonds are by far the most popular diamond shape, taking up 75% of the market for all diamonds sold. They look great with any style of engagement ring setting and are considered the go-to for maximum sparkle. The mechanics of the round shape allow for the perfect reflection of light, if cut with the right quality standards. They are also the only non-fancy “traditional” shape.


Cushion cut diamond.

Cushion cut stones get their name from their resemblance to pillows — square with rounded corners. They tend to have an “antique” feel to them and look particularly appealing when paired with vintage-style settings. For the first century it was around, cushion cut diamonds were actually the most popular diamond shape, surpassing round cuts until the early 20th century.


Princess cut diamond.

Princess cut diamonds were created in 1980 and are now the most popular fancy cut, particularly for engagement rings. With a square, sometimes slightly rectangular shape, they do a beautiful job of reflecting light and creating sparkle. Like round cut diamonds, they tend to blend well with almost all engagement ring setting styles.


Emerald cut diamond.

Emerald cut stones are rectangular-shaped, with unique facets that produce a “hall of mirrors” effect, as opposed to the traditional sparkle of a round or similar cut. This emphasizes the dark and light areas, offering drama and elegance to this unique shape. If you’re looking to elongate the hand, emerald diamond shapes are the way to go — just remember that inclusions are often easier to see in an emerald cut, so you may need a higher clarity level for that perfect-looking stone.


Marquise cut diamond.

The marquise cut is similar to a football shape and was named after the Marquise of Pompadour. Their narrow shape gives off the illusion of length and size, and with the largest crown surface area of any diamond shape, they are great to maximize your budget for size. They can vary in narrowness depending on the cut and look great in many engagement ring settings, including solitaire, three-stone, and pavé.


Heart cut diamond.

Heart-shaped stones are exactly what they sound like — the well-known symbol of love cut from a diamond. While less popular in traditional engagement rings, they can often be found ornamenting right-hand rings, pendant necklaces and more.


Oval cut diamond.

Ovals combine the traditional brilliance of a round diamond with a more contemporary, standout cut. They also have an elongated shape, which can sometimes give the illusion of making them appear larger and lengthen the finger of those wearing them. They look particularly beautiful in a solitaire setting, but can easily blend into any setting because of their sophisticated shape.


Pear cut diamond.

As a combination of a round and marquise shape, pear-shaped diamonds offer the best of both worlds. They provide the finger-slimming effects of the marquise with the superior sparkle of the round cut. If you’re looking for a diamond shape that offers uniqueness and chic style, pear cuts are the way to go. Whether it’s partnered with baguette side stones, a gorgeous halo, or taking center stage in a solitaire setting, pear-shaped stones always make an impact.


Radiant cut diamond.

Radiant cut diamonds are a cross between a cushion and princess cut, with a square shape and cropped, angular corners. They provide amazing sparkle and a vibrant stone that offers a little something different. With this simple but not understated shape, solitaire or pavé settings will bring out the particular sparkle of radiant stones.
