When it comes to diamonds, size matters. The allure of a large, dazzling diamond is undeniable. However, not all diamonds are created equal in terms of perceived size. One crucial factor that significantly influences the size perception of a diamond is its shape. The shape of a diamond plays a pivotal role in how big it appears to the naked eye. If you’re wondering what diamond shapes look biggest, then read on!

Understanding Diamond Shapes

The impact of a diamond’s shape on the overall appearance cannot be understated, especially if the diamond is the center stone of a diamond engagement ring. Every diamond shape has unique characteristics that affect how it looks and is perceived. The diamond’s shape affects its physical appearance, brilliance, fire, and scintillation.

Selecting the appropriate diamond shape is vital to achieving the desired size perception. The shape plays a significant role in creating the illusion of a larger diamond, even if the carat weight remains unchanged. A fancy shape diamond, such as an oval or marquise cut, has elongated outlines that visually lengthen the finger, giving the impression of a larger diamond. In contrast, with their symmetrical and well-proportioned facets, round brilliant cut diamonds optimize light reflection and create the impression of a bigger stone.

Choosing the right diamond shape requires careful consideration. By learning about the impact of different diamond shapes on the overall appearance and perceived size, you can make an informed decision that reflects your taste and style. This approach will help you create a stunning diamond ring that captures the attention and admiration of everyone.

Difference Between Diamond Shape and Diamond Cut

Diamond shape refers to the geometric outline or contour of the diamond. It describes the physical appearance of the diamond when viewed from above.

On the other hand, diamond cut refers to the quality of the diamond’s faceting and how well it interacts with light. It encompasses the precision, proportions, symmetry, and polish of the diamond’s facets, determining its brilliance, fire, and overall sparkle.

While shape focuses on the outline, cut focuses on the craftsmanship and optical properties of the diamond.

Factors Influencing Diamond Size Perception

Several key factors contribute to the perception of diamond size, and understanding them is essential to selecting a diamond that appears bigger.

One of the primary factors is the diamond carat weight, which refers to a diamond’s mass. Generally, a higher carat weight corresponds to a larger diamond. However, it’s important to note that carat weight alone does not determine how big a diamond shape looks.

The cut quality affects how well a diamond interacts with light, ultimately impacting its brilliance and sparkle. A well-cut diamond reflects and refracts light optimally, creating a dazzling appearance and giving the illusion of a larger size. A poorly cut diamond, on the other hand, will have a reduced brilliance and a diminished size appearance.

Diamond color and clarity can also influence perceived size. Diamonds with higher color grades, such as those closer to colorless, can create the illusion of a larger diamond due to their ability to reflect more light. Similarly, diamonds with higher clarity grades, indicating fewer internal and external flaws, tend to have better light performance, enhancing the perceived size.

Diamond Shapes That Appear the Biggest

Several diamond shapes stand out when discussing which shapes look the biggest.

Round Brilliant Cut Diamond

Round cut diamonds are highly valued for their exceptional ability to reflect and refract light. The symmetrical design of a round diamond enhances its brilliance, resulting in a stunning visual effect. This superior light performance gives a round cut diamond the impression of it being larger than other diamonds of the same carat weight.

Oval Cut Diamond

The elongated shape of an oval diamond can create the impression of a larger surface area. The elongation visually elongates the finger when the stone is set in a ring, contributing to a more significant overall appearance. Additionally, oval cut diamonds have well-distributed facets, enhancing light dispersion and adding to the illusion of size.

Emerald Cut Diamond

Emerald cut diamonds possess a distinct charm that sets them apart. Their rectangular shape with step-cut facets creates a hall-of-mirrors effect that captivates all viewers. Although they may not have the same brilliance as round or oval diamonds, the elongated silhouette of an emerald cut diamond and its characteristic charm can give the impression of a larger stone than its carat weight would indicate.

Pear Cut Diamond

Pear-shaped diamonds are recognizable by their unique teardrop shape. The tapered point at one end and the rounded edge at the other give the diamond an elongated appearance, which can make it appear larger than it is.

Other Considerations

When choosing a diamond, it’s important to take into account other factors besides its shape.

Personal Style

Your personal style and aesthetic preferences should play a significant role in the diamond shape you choose. While some shapes may make the diamond appear bigger, selecting a shape that reflects your unique style and complements your overall jewelry preferences is more important.

Whether you prefer timeless elegance, contemporary sophistication, or something more unconventional, selecting a diamond shape that aligns with your style is essential in creating a piece of jewelry you’ll cherish for years to come.


Budget is another practical consideration when selecting a diamond shape. Different shapes may vary in price due to popularity, availability, and the amount of rough diamond wastage during the cutting process. To make the most of your purchase, set a budget range and explore diamond shapes within that range.
