Oval Diamond
The oval cut is an elongated version of the round brilliant cut, combining the brilliance of a round diamond with a more unique, oval shape. With 58 facets, oval shaped diamonds produce the same sparkle and fire as the round cut, but its elongated shape creates a larger appearance. In recent years, oval cut diamonds have surged in popularity, showing up on the fingers of celebrities like Hailey Bieber and Blake Lively.
Because of its elongated proportions, the oval cut is especially flattering on shorter or wider fingers, creating a lengthening effect while maximizing perceived size.

Marquise Diamond
The marquise cut diamond is an elongated diamond with pointed ends, resembling the shape of an eye. This cut was created in the 18th century for King Louis XV of France. According to legend, it was designed to resemble the shape of the lips of his mistress, Madame de Pompadour. Due to its elongated, unique shape, the marquise cut maximizes carat weight, giving the diamond a larger surface area and making it appear more substantial than other cuts.
Like oval cuts, marquise diamonds can elongate the look of the finger, making them a strong choice for creating a slimming, lengthened effect.

Round Brilliant Cut Diamond
The round brilliant cut is the most popular and timeless diamond shape, accounting for approximately 75% of all diamonds sold. It features 58 facets, which are carefully arranged to maximize the diamond’s ability to reflect light. Since this diamond shape maximizes light reflection, it is the most forgiving of inclusions and blemishes. Pro tip: While all round brilliant cut diamonds are round, not all round diamonds (sometimes called a classic round diamond) are brilliant cut—the round brilliant cut is a specific style of cut for a round-shaped diamond.
Its balanced proportions make it universally flattering across all hand shapes, which is part of its enduring appeal.

Asscher Cut Diamond
The Asscher cut is a square version of the emerald cut, characterized by its cropped corners and step-cut facets, which gives it more of a square shape. Developed in the early 1900s by Joseph Asscher, a member of the renowned Asscher family of diamond cutters from Amsterdam, the Asscher cut has a vintage, art-deco-inspired design. Like the emerald cut, it emphasizes clarity and color, and its large, open facets can reveal the internal characteristics of the diamond.
Its symmetrical, structured shape works best on longer fingers where its bold geometry can shine.

Emerald Cut Diamond
The emerald cut is a rectangular shape with trimmed corners and step-cut facets. (Other popular diamond shapes in the step cut family include Asschers and baguettes.)

Heart-Shaped Diamond
A heart-shaped diamond is a modified brilliant cut that combines the shape of a traditional round diamond with a distinctive heart shape, making it a popular choice for romantic occasions such as engagements or anniversaries. It features a rounded top with a cleft (indentation) at the point, resembling a heart.
Because of its bold, symbolic shape, it tends to stand out best on smaller hands where the silhouette remains clearly defined.
Diamond Shape vs Diamond Cut:
What’s the Difference?
When shopping for an engagement ring, two terms often come up: diamond shape and diamond cut. While they may seem interchangeable, they refer to distinct aspects of a diamond. Diamond shape describes the diamond’s overall form—whether it’s round, oval, pear, or another silhouette. Diamond cut, on the other hand, refers to how well the diamond has been faceted to reflect light, which impacts its brilliance and fire. For instance, two diamonds with the same shape—like a round diamond—can have different levels of sparkle based on their cut quality. Understanding both factors ensures you select a diamond that not only has the aesthetic you desire but also maximizes its brilliance.
What is a Fancy-Shaped Diamond?
According to the Gemological Institute of America (GIA), a fancy-shaped diamond refers to any diamond shape other than round. This includes popular shapes like oval, pear, marquise, cushion, emerald, Asscher, radiant, princess, and heart-shaped diamonds. Unlike round brilliant diamonds, which are cut for maximum sparkle, fancy shapes offer a variety of styles, proportions, and facet arrangements, allowing for unique expressions of personal style.
