Guide to Diamond Shapes

A diamond’s shape makes it unique and distinguishable. Each shape portrays distinct characteristics as well as different features of a diamond. They are cut in a variety of shapes that double the brilliance of a diamond. Round brilliant cuts are highly admired in the world due to their unrivaled fire and brilliance. There are two distinct aspects to the shape and cutting process of a diamond: the external look and how many facets the stone has.

Diamond cut and diamond shapes: The difference

When buying a diamond, it becomes essential to understand the difference between a diamond shape and a diamond cut that will help you to choose the best diamond for your jewelry or engagement ring.


The diamond shape refers to the diamond’s outline shape when you look at it from the top down. Round, Oval, Princess, Emerald, Cushion, Heart, Marquise, Asscher, Pear, Trapeze, and Baguette are all shapes referred to as “fancy shapes,” and these diamonds, as well as gemstones, are used in a range of different styles of jewelry. When selecting your ideal diamond shape, it will also help you to consider: the type of ring you want, your and your partner’s finger shape, or just a design you like.


As opposed to the diamond’s shape, the cut is a measure of how proportioned and symmetrical the diamond appears.

As a result, the amount of light emitted by the diamond will influence how much it sparkles. Brilliance, fire, and scintillation are all terms used to describe different types of light reflections.

The Most Popular Diamonds Shapes

1. Round Brilliant Diamond

When compared to other diamond shapes, the history of the round-cut diamond is a little different. It took decades to achieve and perfect this kind of diamond cutting, which is currently incredibly popular in today’s market. It was the jewelers’ attempt to find a natural diamond with the greatest number of facets and the greatest amount of shine. This diamond is ideal if you want to flaunt your trendy, sophisticated, and classy side while yet remaining affordable. Despite the fact that there are numerous other types of cuts available today, the most popular cuts have been used to manufacture engagement rings and other jewelry for a long time. Currently, the brilliant-cut is the most popular shape for round diamonds because it has more facets and angles than the previous diamonds, which were cut with wider, more open facets while they were still in the ground.

The round brilliant cut diamond has a total of 58 facets that are divided into three sections: the crown (top), the girdle (widest part), and the pavilion (base). The round brilliant cut diamond’s fire and brilliance are calibrated using a precise formula in order to produce the most fire and brilliance possible. When cutting a rough stone in order to shape a round diamond, more material is removed than is needed, which is why the cost of each carat becomes higher. Round brilliant diamonds account for the vast majority of diamonds currently in existence. Martin Flyer offers the most sought-after diamond shapes in the world for engagement rings, necklaces, earrings, and bracelets, as well as other jewelry items.

2. Oval Shaped Diamond

The Oval cut diamond, which is simply an enlarged round brilliant cut diamond, was created in the mid-1900s and has been in use ever since. Despite the fact that oval diamonds have the same brilliance as round diamonds, their distinctive shape sets them apart. This is a popular diamond’s shape because it seems larger than a round diamond of the same carat weight, which makes it more valuable. At Martin Flyer, the oval diamond’s shape is extremely attractive because it can make one’s fingers appear longer and thinner.

 Because an oval diamond can elongate your hands, any ring that has this diamond shape will have an air of sophistication about it. The oval diamond is fragile as it has rounded edges. In contrast to the sharp points of the marquise cut, oval diamonds add a delicate touch to the length of this stone. Choosing the right diamond color for this sort of stone is a little more difficult. It is required to increase the color grade in order to ensure that the ends seem colorless, as the rounded ends tend to reveal more color than a round diamond would otherwise.

3. Pear Shaped Diamond

A pear-shaped diamond engagement ring is a popular choice among ladies who appreciate its unique appearance. Pear-shaped diamonds can be used in a variety of settings, including engagement rings. A pear-shaped diamond is crafted just like a teardrop, but with a flatter and bigger bottom and a thin point at the top of the diamond, just like a teardrop.

Its teardrop-shaped design is distinctly memorable. Ring with a pear-shaped design can be worn in either an upwards or downwards orientation, depending on how you want it to look. Since it has been faceted, inclusions are often obscured by the point, which makes them less obvious. Pears that are longer in length have a slimming effect on the fingers. The optimal cutting ratio is between 1.5 and 1.7. At the diamond’s tip, there are several flaws and extra facets can be found. To avoid chipping, at the tip, there should always be a prong.

4. Emerald Shaped Diamond

Emerald-cut diamonds were among the first diamond cuts to be discovered in the world. In spite of this, due to their resemblance to other diamond-cutting procedures, they did not become standardized until 1940. Because colored gemstones and high-quality diamonds both look amazing in the emerald cut. Don’t save on the diamond quality if you opt for this style of engagement ring design.

Emeralds are known for their symmetrical shine, which makes them stand out among other gemstones. The emerald diamond cut is a symbol of unity since it is properly proportioned and enhances the diamond’s brilliant brilliance. Because of its tiered faceting, the emerald cut is often referred to as a “step cut.” In total, the diamond has roughly 25 crowns, 25 pavilions, and 8 girdle facets, each with three rows of bottom steps and three rows of upper steps. Given that an open setting allows for a greater view of the color of a diamond, bezel or closed settings are favored when the diamond has a lower color quality.

5. Elongated Cushion Cut Diamonds and Radiant Cut Diamonds

Making the right choice for the diamond’s shape is essential since it has an impact on the overall appearance and beauty of the ring. If the more common diamond shapes do not appeal to you, other cuts like an elongated cushion or radiant cut diamonds are popular alternatives.
