The Complete Catalog Of Diamond Shapes: A Buyer's Manual

When selecting the perfect diamond for an engagement ring, a piece of jewelry, or any other significant purchase, the shape of the diamond is one critical factor to consider. Each shape has unique characteristics and conveys different styles and meanings. Here, we'll explore various diamond shapes, their attributes, and what makes each special.


Understanding Diamond Shapes


Round Brilliant Cut

The round brilliant cut is the most popular diamond shape, known for its exceptional brilliance and fire. It typically has 58 facets, which maximize light reflection and sparkle. Due to its timeless appeal and superior light performance, the round brilliant cut remains the top choice for many buyers.


Princess Cut

The princess cut diamond is second only to the round brilliant in popularity. It offers a modern square or rectangular shape with pointed corners. Its complex faceting pattern creates a high degree of sparkle. The princess cut is ideal for those who want a contemporary twist on the traditional round diamond.


Cushion Cut

Cushion-cut diamonds have rounded corners and larger facets, combining a vintage feel with a soft, romantic appearance. This shape, often described as a pillow shape, has gained popularity for its ability to enhance a diamond's brilliance and clarity.


Emerald Cut

The emerald cut features a rectangular shape with step-cut facets, giving it a sophisticated and elegant look. It's renowned for its clear, open table, showcasing the diamond's clarity and color. Celebrities often favor the emerald cut for its understated yet glamorous appeal.


Asscher Cut

Similar to the emerald cut but more square, the Asscher cut features step-cut facets and a high crown. Known for its Art Deco charm, the Asscher cut emphasizes clarity and brings vintage elegance to any piece of jewelry.


Radiant Cut

The radiant cut combines the emerald and Asscher cuts' stylish, square shape with a round cut's brilliance. Its trimmed corners make it versatile for various settings and styles, offering a unique blend of elegance and sparkle.


Oval Cut

The oval cut diamond provides the brilliance of a round cut but with a distinctive elongated shape. This silhouette can create the illusion of greater size, making the finger appear longer and more slender. Oval cuts are ideal for those seeking a classic yet unique look.


Pear Cut

Resembling a teardrop, the pear cut diamond combines the best aspects of the round and marquise cuts. It's a versatile and graceful choice that looks stunning in various settings, from engagement rings to pendants.


Marquise Cut

The marquise cut diamond features an elongated shape with pointed ends, maximizing carat weight and creating a striking appearance. This cut is perfect for those who desire a bold, dramatic look and want their diamond to stand out.


Heart Cut

The heart cut diamond is a symbol of love and romance, boasting a unique heart shape. It requires meticulous cutting to ensure symmetry and brilliance. The heart cut is ideal for those looking to express their love through their choice of diamond.


Trilliant Cut

The trilliant cut, also known as the trillion cut, is triangular with slightly rounded edges. Its sharp, fiery brilliance makes it a popular choice for side stones, adding an extra layer of sparkle to any piece.



Factors Influencing Diamond Shape Selection


Lifestyle Considerations

When choosing a diamond shape, consider your lifestyle. For instance, shapes like the round brilliant and cushion cut are versatile and resilient, making them suitable for daily wear. Conversely, shapes with pointed edges, like the marquise or pear, may require more protective settings.


Personal Style

Diamond shapes reflect personal style. For example, the classic round cut suits those with traditional tastes, while the Asscher or emerald cuts appeal to lovers of vintage aesthetics. Selecting a shape that aligns with your style ensures long-term satisfaction with your purchase.


Setting Compatibility

The setting you choose can enhance or diminish a diamond's natural beauty. Some shapes, like the princess and radiant cuts, work well in various settings, from solitaires to halos. In contrast, unique shapes like the heart or pear may require custom settings to showcase their distinctiveness.


The Significance of the Four Cs

While the shape is crucial, understanding the four Cs – cut, color, clarity, and carat weight – is equally essential in making an informed decision.


  • Cut: The cut influences a diamond's brilliance. Different shapes may exhibit varying levels of sparkle based on their cut quality.

  • Color: The less color a diamond has, the higher its grade. Round brilliant cuts can mask color better than other shapes.

  • Clarity: This measures the presence of inclusions or blemishes. Shapes with larger, open tables, like the emerald cut, require higher clarity grades.

  • Carat Weight: The weight of the diamond affects its perceived size. Elongated shapes like oval or marquise can appear larger than their carat weight suggests.
