With our strict standards of quality, we at The Engagement Ring Studio ensure that all of our diamond shapes are of the highest cut and craftsmanship. Our wide-ranging collection of GIA and EGL USA graded diamonds include every shape from the classic round brilliant to fancy shapes such as emerald cut, cushion cut and the Asscher cut.


Choose Your Diamond Shape

Each individual diamond shape has its own unique properties. The way each diamond reflects light and shines brilliantly all depends upon its shape and the way it is cut.


Round Cut Diamond

What we know as the modern round brilliant Cut Diamond has been a highly desired diamond shape in engagement and wedding rings for almost a century. The most flexible of all diamond shapes, the round cut diamond mounts perfectly into most settings, whether you are creating a brilliant engagement ring, a beautiful diamond pendant or earrings.
The round brilliant diamond features 58 precision-cut facets that magnify the brilliance and sparkle the viewer sees within the heart of the stone. As this popular cut has the most extensive range of color and clarity of any shape available to date, the round brilliant is a highly prized and much sought-after shape that will remain a staple diamond cut for many years to come.


Princess Cut Diamond

The next most popular cut after the round brilliant is the princess cut diamond. This diamond shape looks stunning in both classic and modern settings and is a very flexible choice when considering which diamond shape is right for you. The face-up shape of this diamond is square to slightly rectangular with pointed corners and chevron-shaped facets that magnify scintillation and fire of the diamond\. This unique faceting style displays a good degree of brilliance, making it a lovely choice if you’re going for something different than a round brilliant without having to sacrifice scintillation and fire. GIA defines the princess cut as a square modified brilliant or a rectangular modified brilliant cut.
These diamonds will appear perfectly square in the length to width ratio range 1.0-1.05; it will appear very near perfect within the 1.06-1.09 range.


Emerald Cut Diamond

The emerald cut diamond is one of the more unique, elegant and sophisticated diamond choices out there. Flaunting an unmatched vintage look, this unique cut features a large table that exhibits the clarity and transparency of the diamond. The emerald cut is a step cut; its primary characteristics are straight, tiered facets that appear like a mirrored staircase. Its most distinct and signature characteristic is cut corners on the outer edges of the diamond.
In searching for the perfect emerald Cut Diamond, make sure to maintain a high clarity rating. The Engagement Ring Studio recommends clarity grades of VS2 and higher with a thorough visual inspection to ensure that no inclusions or blemishes effect the appearance or clarity of the diamond.


Marquise Cut Diamond

The marquise Cut Diamond is truly one of a kind among all diamond shapes. The curved, oblong shape of this diamond is distinctive and flattering. This regal shape originated in the court of King Louis XIV, where he commissioned it himself, and is also known as the “navette” cut, which translates to “little boat” in French due to it’s signature shape.
The marquise cut is a modified brilliant cut that creates an outstanding standard of brilliance while still maintaining the maximum amount of carat weight and millimeter size. The marquise cut diamond’s elongated shape also makes the finger of the ring wearer appear longer and more slender.


Heart Cut Diamond

A heart shape diamond is a distinctive cut that symbolizes true love and romance for the ring wearer. This diamond cut sets stunningly in rings as well as pendants, and beautifully displays the fire and brilliance in the heart of the diamond.
Originally a pear shape, the heart shaped diamond features a small notch at the top that only the most skilled diamond cutters may attempt. This distinct cut also features symmetry and a balanced length to width ratio that is an important consideration with heart shaped diamonds, as diamonds that are cut incorrectly can appear distorted and uneven.


Pear Cut Diamond

The pear shape is a brilliant cut with a rounded bottom that comes to a distinct point on the opposite end of the diamond, making its cut stand out while the rounded side of the pear diamond contributes to its brilliance.
The pear’s lengthy silhouette is a flexible and pleasing choice for the ring wearer, as this lends a classical and beautiful appeal.


Asscher Cut Diamond

The Asscher cut is very similar to the emerald cut. Both of these cuts are step cuts that have tiered facets and reflect light in a mirror-like manner. The Asscher cut diamond, however, is square shape rather than rectangular. The step cut accentuates the clarity of the diamond, and it is perfect for featuring higher clarity diamonds.
This eye-catching cut was developed in 1902, and its geometric style was popular during the Art Deco period. Since then, the Asscher cut has skyrocketed in popularity over the last ten years and is chosen by those looking for a diamond cut that expresses their flair.


Oval Cut Diamond

Brides with a preference for the original yet unique go for the oval diamond. More rare than round and princess-cut diamonds, oval diamonds are graceful with an elongated shape but still sparkle with the life and brilliance of a round cut diamond. Like the marquise, the oval Cut Diamond makes the ring wearer’s fingers appear slimmer.
Its length to width ratio determines the overall profile of an oval. For a classically oval shape, The Engagement Ring Studio recommends a length to width ratio in between 1.33 and 1.66. The oval features 58 facets- the same as a round brilliant, but has a larger table.


Radiant Cut Diamond

The radiant cut is one known for having brilliant facets that produce a bright and fiery effect due to magnified light return. It is a brilliant cut that may be either square or rectangular with cut corners. For people who enjoy clean, linear shapes but want something that stands apart from a princess cut, a radiant cut diamond is a great choice. Whether standing alone as a solitaire or surrounded by other diamond accents, this fiery cut looks fabulous in a variety of settings and is extremely versatile.
The length to width ratio determines how rectangular the radiant cut will be. A ratio of 1.00 to 1.05 will create a square shape, and from 1.30 to 1.50 will produce a rectangle.

Cushion Cut Diamond

Originating in the 1800’s, Cushion Cut Diamonds are an antique cut that remain popular to this day. Cushion Cut Diamonds are known as the “candlelight” diamonds, as they feature larger crown facets that strongly accentuate the fire of a diamond and increase their brilliance, which is most noticeable by candlelight.
The final shape of a Cushion Cut Diamond depends entirely on your taste, as they can be rounded squares or rectangular squares. There is no correct shape or ratio when choosing a gorgeous cushion cut shape, so refer to the length to width ratio to visualize the general shape of the stone you prefer.
