Which Diamond Shape is Right for You?

What is a Diamond Shape?

Diamond shape refers to the overall geometric appearance of the stone. Diamond shapes have their own appeal with the cuts for each shape bringing out the brilliance of the stone. While the cut is one of the 4 C's by which the quality of a diamond is graded and evaluated, the shapes of diamond aren’t. The cut of the diamond focuses on the facets and angles while the diamond ring shapes appeal to aesthetics.

Among the most popular shapes are the round diamond and princess cut. Do not feel yourself limited to these since we offer other amazing cuts and designs, including unique shapes such as the pear and heart. We also offer re-emerging cuts like the square cushion. Whichever shape and cut you choose, always let your sensibility and style dictate the appropriate diamond shape for yourself or for your loved one.

Round Cut Diamond Shape

Round Brilliant Diamond Shape


Developed by Marcel Tolkowsky in 1919, the most popular diamond shape on the market remains the round brilliant diamond shape. This gives the largest flexibility within the four C's, you will want to select higher quality grades to bring out the most brilliance within a round diamond.

Round diamond shapes tend to create the highest waste from cutting the polished diamond from the rough. This excess waste, coupled with the high demand, makes the round brilliant cut diamond more expensive compared to other "fancy" shaped diamonds.

Princess Cut Diamond

Princess diamond shapes are the second most popular shape and mostly come as square shaped, but occasionally can be elongated. They can have as much brilliance as rounds and are sometimes referred to as square brilliant diamonds. The corners of the princess cut are 90 degree points. Princess diamond shapes are not graded for cut by the GIA as there are no 'ideal' measurements, but do have a polish and symmetry grading.

The princess cut was designed by Betzalel Ambar and Israel Itzkowitz in the 1980s. Though a much newer cut compared to the round brilliant, the princess is another highly revered cut for engagement rings because of its flexibility with ring settings.

Cushion Cut Diamond Shape

Those who prefer a vintage feel to their engagement rings will find solace in the beauty of a cushion diamond shape. Around for 200 years, this shape is all about old world charm. Commonly called the old mine cut, cushion diamond shapes are the amalgam of a square cut with round corners. Though subordinate in terms of brilliance to the round cut diamond, a cushion cut displays superiority in fire.

The cushion cut has rounded corners and mildly rounded sides. Cushion diamond shapes can come 'square' or 'rectangle' and the length-width ratio can greatly affect the look of the stone. In some cases, a ring can only be set with either a square or a rectangle cushion cut diamond, depending on the design. For example if it has a fixed halo of diamonds around it.

Radiant Diamond Shape

It’s easy to confuse a radiant shape with a princess shape because of the similarity in structure. Also, you should know that radiant shaped diamonds are considered the first ever square to achieve an integrated and complete brilliant- cut facet on the crown and pavilion. The cut is a bridge between a princess and cushion.

This diamond shape is perfect for combining the silhouette of an emerald cut with the fire and sparkle of a round cut. However, due to its design, this shape requires more in carat weight to maximize its brilliance.

Marquise Diamond Shape

The marquise shaped diamond features pointed ends with a curved middle for an eye-catching look. With a larger surface area than any other diamond shape, this is the perfect ring for anyone looking to get the most size out of their diamond.


Emerald Diamond Shape

This shape is originally meant for emeralds, not diamonds. However, the uniqueness of the emerald shape won the hearts of diamond cutters and jewelers. Unlike a cushion cut, emerald shaped diamonds have less fire. Nonetheless, the shape and long lines allow the light to give the diamond a dramatic and sophisticated appeal.

Emerald diamond shapes are similar in structure to radiant cut diamonds. However, with cut off corners and flat edges, they are a step cut rather than brilliant cut. The step cut gives the appearance of large shimmering mirrors that reflect light out of the face of the large table.

Pear-Shape Diamond Cut

Pear-Shaped Diamond Shape

The pear shape is an altered brilliant-cut, which attempts to incorporate the style of marquise and the round cut. This diamond shape is commonly used for earrings and pendants because of the teardrop-like look. However, its gained popularity for engagement rings due to its vintage feel.

Pear shaped diamonds or teardrops have one side rounded and the other pointed. The slender pear shape will give fingers and hands a slimmer appearance while creating a soft and delicate look.

Oval Cut Diamond Shape

Do you want the brilliance and fire of the round brilliant cut diamond but prefer a much more unique version of it? Oval diamond shapes could be ideal. This shape is a modified version of the round brilliant cut but made slender in shape, giving the appearance of greater size than it is.

Oval diamonds have a classic appearance with a modern twist! It has an incredible brilliance, similar to the round brilliant cut, but also has the advantage of accentuating long, slender finders.

Heart Cut Diamond Shape

Heart shapes are for the true romantics. The symbol of love cut into an eternal-lasting diamond is the special choice for engagement rings.

When choosing a heart-shaped engagement ring, symmetry should be on top of your list. It is important for the two halves of the heart to be of identical size.
