All About Trapezoid Diamonds + What Stones They Work Well With

The beautiful diamond represents passion, luxury and even character. The beauty and splendor of a diamond are characterized by its cut. In this article, we'll explore one of the less familiar but incredibly versatile cuts in the diamond world—the trapezoid diamond. We'll dive deep into its unique attributes, the two primary cutting styles associated with it, and how it complements other stones in jewelry design.

Trapezoid Diamond Education

What are trapezoid diamonds?

Trapezoid diamonds, also known as "trapeze-cut" diamonds, are unique diamond shapes typically used as side stones to enhance the beauty of the center stone in a jewelry piece. The top and bottom are parallel with four sides, while the other two angles are outward, forming a trapezoid shape.

A trapezoid diamond's key characteristics revolve around its symmetry and precision in the cut. The beauty of a trapezoid-shaped diamond lies in the balance between its length and width📐, its alignment with the center stone, and its ability to draw the eye toward the centerpiece. These diamonds are excellent for adding size and sparkle to a jewelry piece without drawing attention away from the primary stone.

While commonly used as side stones, trapezoid diamonds are flexible enough to play center stage. Their geometric precision allows them to fit snugly next to various cuts, enhancing the brilliance of a center stone or adding their shine as solitaires. These gems also cater to different jewelry styles, from contemporary designs to vintage aesthetics, making them a beloved choice for many designers and diamond enthusiasts.❤️

Step-cut trapezoids vs. Brilliant-cut trapezoid diamonds

Regarding trapezoid diamonds, two major cutting styles stand out—the brilliant cut and the step cut. These cuts have unique aesthetic features and light performance characteristics that suit different jewelry styles.

The brilliant-cut trapezoid diamond features triangular and kite-shaped facets, which can amplify the diamond's brilliance. These diamonds radiate light, making them a perfect complement to other brilliant-cut center stones like round or princess cuts.

On the other hand, step-cut trapezoid diamonds featuring concentric rows of parallel facets present a subtler, more understated elegance. A step-cut trapezoid diamond's clean lines and geometric symmetry emit an Art Deco-style realness, making them a perfect match for other step-cut center stones like emerald and Asscher cuts.

In a trapezoid diamond ring, these side stones can add breadth and highlight the center stone's shape and cut, regardless of whether they are brilliant or step-cut trapezoids. When considering an emerald-cut diamond ring with trapezoid side stones or an Asscher-cut diamond with trapezoid side stones, the parallel lines of the step-cut trapezoids accentuate the center stone's clean angles and draw attention to its inherent elegance.✨

Choosing between a step-cut or brilliant-cut trapezoid diamond largely depends on the aesthetic you aim for and the cut and style of the center stone you wish to emphasize. Both offer their unique allure, ensuring your jewelry piece is nothing short of stunning.

But these diamonds aren't just about looks. Their unique cuts also influence their light performance. With their fewer, larger facets, step-cut trapezoids create a mirror-like effect, while brilliant-cut trapezoids boast more parts, producing heightened brilliance and fire. This difference in light play can significantly affect your jewelry piece's overall appeal and appearance.

A unique version: Crescent trapezoid diamonds

Crescent trapezoid diamonds are an exciting version of the traditional trapezoid cut. They feature an elegant crescent shape, which gives them an extra dose of charm and intrigue. Aesthetically, crescent trapezoid diamonds are an excellent choice for enhancing a variety of center stones with curved lines, thanks to their unique shape.

The crescent trapezoid diamond works well with round or oval center stones in three-stone settings. Their curvaceous form elegantly contrasts with these rounder shapes, enhancing the center stone's brilliance while adding a distinct visual appeal.🤗

This combination creates a harmonious interplay of shapes that can enhance a ring's overall visual impact. In addition, the crescent trapezoid's distinctive shape can subtly shift the viewer's gaze toward the center stone, making it appear larger and more magnificent.

Trapezoid diamonds vs. Tapered baguette diamonds

While trapezoid and tapered baguette diamonds share a common geometric style, there are notable differences between the two. Tapered baguette diamonds are generally longer and more slender, creating an elongated trapezoidal shape. In contrast, trapezoid diamonds are broader and shorter, presenting a more compact trapezoidal appearance.

👉🏻These diamond shapes highlight and enhance a center stone, but their effects on the jewelry's overall look can vary. Tapered baguettes lend a sleek, linear quality to jewelry, often paired with emerald or Asscher cut center stones. Conversely, with their bolder appearance, trapezoid diamonds can add significant visual weight to a piece, making them ideal for larger and more brilliant center stones.

The selection between these two diamonds may also depend on the jewelry's overall design and the wearer's preference. Tapered baguettes can add a vintage touch, while trapezoid diamonds offer a modern twist. Ultimately, the choice depends on the desired aesthetic, personal style and the particular design of the jewelry piece.

What to consider when employing trapezoid diamonds for your jewelry?

There are several critical considerations for using trapezoid diamonds in your jewelry.  

  • The center stone's precise measurements.
    • The trapezoid diamond side stones should be proportional to the center stone (to maintain a balanced look).
    • The center stone's shape, cut, and style should also be considered (as trapezoid diamonds enhance certain amounts better than others).
  • The overall aesthetic of the jewelry piece.
    • Do you want the work to have a bold, contemporary look, or do you prefer a more classic, understated style?
  • Quality of the trapezoid diamonds
    • The four Cs should be carefully considered: cut, clarity, color, and carat weight.

It's essential to consider the diamond's setting. Certain settings might enhance or detract from a trapezoid diamond's beauty. Prong settings can maximize the diamond's exposure to light, while bezel settings can provide a sleek, modern look. Understanding how each setting type interacts with the trapezoid diamond's unique shape and cut can help ensure you make a choice that brings out the best in your diamonds.


With their unique shape and versatile application, trapezoid diamonds offer a fantastic opportunity to create a truly standout piece of jewelry. Whether used as side stones in a three-stone ring or as striking components in a contemporary design, trapezoid diamonds provide an additional level of elegance and interest.

Considering the factors outlined in this article, you can confidently incorporate trapezoid diamonds into your jewelry, creating stunning and personal pieces.🙌🏻
