Diamond Shape Guide

With so many diamond shape options, it’s easy to get confused which shape is your favorite or matches your style. We’ve taken the time to highlight the 10 most popular diamond shapes to help narrow down your search.

One of the Four C’s: Cut

Diamonds are graded based on four criteria: cut, clarity, color, and carat. Diamond shapes fall under the cut category. A diamond is cut in specific shapes to maximize shine and create symmetry in the diamond.

Diamond Shape Guide

Diamonds can vary in shape based on personal preference and maximizing the way light reflects.


round diamond ring

Round diamonds are a popular choice among many. This is due to the fact that this shape maximizes the amount of light that reflects off the diamond. This style can be attributed to timeless and classic style. The round shape has been around for a very long time and continues to be a classic symbol among diamond rings.


The oval shape was first introduced in the 1700s. It’s a similar option to the round diamond, but gives a different look while still maintaining a classic feel. Because of the elongated shape, oval diamonds on rings make your fingers appear slimmer and longer.


princess cut diamond

The princess shape is the 2nd most popular ring shape after the round shape. It is recognizable by its square shape. This shape grew popular in the 1980s and still is gaining notoriety today. If you prefer a square diamond cut rather than the traditional round shape, the princess cut may be for you!


The emerald shape is attributed to the cut of actual emerald stones. Emerald diamonds are rectangular. This cut on diamonds produces a half-of-mirrors effect. Emerald cut is a great option if you want your diamond ring to display elegance and refinement.


Asscher diamonds are very similar to the emerald cut, but they are more square-shaped than rectangular. This cut was introduced by the Asscher brothers in the early 1900s, but this shape didn’t see a spike in popularity until the 2000s.


The radiant cut can be defined just as its name states. This brilliant cut is vibrant, containing 70 facets on the stones. It produces a striking reflection of light and in return, creates a stunning shine. This is one of the most durable cuts, so if you tend to put your jewelry through a lot, then you should consider the radiant cut.


cushion cut ring

The cushion cut resembles a pillow. Cushion diamonds are square shaped with rounded corners. This is a popular cut with celebrities, with Kim Kardashian being one of the most notable owners of a cushion-cut ring.


Red diamond ring

The pear shape is often referred to as a “teardrop” shape. It has been said that a pear shaped diamond represents “tears of joy.” Like the oval shape, pear diamonds on rings can make the fingers appear slimmer.


The marquise diamond is similar to the pear shape, but doesn’t have a rounded bottom. This is a vintage looking shape and was popular in the early 1900s. The marquise diamond is beautiful, but simple enough to allow for endless customizations. If you are looking for a one-of-a-kind ring, keep the marquise diamond in mind.


Last, but certainly not least, is the heart diamond. Just as the name states, the heart diamond is shaped like a heart. Typically, these diamonds start off as a pear diamond and are altered to look like a heart. These are a great symbol of love and are in very low demand so there is a very good chance that not many will have a ring like yours!
