Diamond shape is possibly the single decision that will have the biggest impact on your engagement ring. While which metal, setting, and carat size you choose will all play a role in your ultimate engagement ring, diamond shape is often one of the first things people notice.  

The shape of a diamond can drastically alter the look of the ring, the way it catches the light, and how the stone sits on your hand. With any of the popular diamond shapes on the market, the idea behind the cut is to leave as much of the top of the stone intact as possible. This allows light to filter through and reflect the natural sparkle of the stone. Each diamond shape has different facets and cuts that help to make the diamond shine.

With more than ten different possible shapes, its easy to get overwhelmed while shopping. Diamond cut can reflect your style as much as the setting. Here is a quick overview of the most popular diamond shapes that you are likely to see while shopping for an engagement ring, and how to choose one.

The Go-To Guide To Your Perfect Diamond Shape


The round shaped diamond is by far the most popular choice for engagement rings around the world, for a few reasons. Round is a safe bet if you arent sure what kind of diamond your fiance prefers, as it is universally popular and shaped to capture the most light when worn. Its also likely to please a woman with traditional style who doesnt like anything too unique or funky.

Square or Cushion

Eye catching and unique, the distinctive shape of a square cut diamond draws the eye as it stands out against the finger. A square shaped stone is best for women with long fingers, as it can make short fingers look even shorter.


The pear-shaped diamond is less like the fruit shape and more like a teardrop, with a rounded bottom that comes up to a pointed tip. Pear shaped diamonds saw a surge in interest in early 2018 when Ariana Grande wore a pear-shaped diamond engagement ring during her short-lived engagement to Pete Davidson. Sources said she was drawn to the ring because it reminded her of the teardrop emoji symbol.  Pear shaped diamonds are said to make short fingers appear longer and stand out thanks to the pointed shape, which refracts extra light.


The emerald is a rectangular shape with multiple long facets cut along each side to encourage the light to reflect and sparkle. These are called stepped cuts, and they encourage light refraction. This cut can make the diamond attract more light than other shapes like a round or square cut. Fashionable and unique, many celebrity women love emerald cut diamonds for both modern and vintage-inspired engagement rings.


Like the emerald cut, a princess cut is a variation on a geographic shape. While the top of the stone is a square or rectangle, the bottom side comes down to a point. This inverted pyramid shape is due to the beveled cut, which creates multiple beautiful facets. A relatively new shape, the princess cut originated in the 1960s and quickly became the second most popular shape for engagement rings, behind the round shaped stone.


A heart shaped diamond can stand out in a sea of engagement rings, because you do not see as many of them as the more traditional shapes. For obvious reasons, a heart shaped diamond is a romantic choice for an engagement ring.
