A Closer Look at Trapezoid Cut Diamonds



The Evolution of the Brilliant Trapezoid Cut Diamond
The Trapezoid, also known as the Trapeze Cut is a relatively new shape in the world of long-established and dominant classic diamond cuts. It has evolved from the equally respected Baguette and Taper Cuts and is growing in appeal by the day for use as side stones.
Why the Trapezoid?
The Trapezoid, thanks to its elongated bottom side, yet short top provides a stunning choice for side stones that is hard to beat, along with its extended lines and high surface area. The Trapezoid Cut plays tremendously well with other cuts, and is often seen aiding Radiant and Princess Cut Center Stones, and a rising trend has been to combine trapezoid side stones with straight bullet cut diamonds in five stone rings.
The Trapezoid Brilliant Cut Demands Mastery
Unlike most diamond cuts, the trapezoid cut diamond does not have what is known as an optimal width to length ratio, and as such, the ability to adapt to each piece and create a stone that returns the ideal light and proportions. But that’s not all. As a side stone, it takes time and sophistication to find the perfect center stone to match it.
Center Stone Ideas for Brilliant Cut Trapezoid Side Stone Diamonds
The Brilliant rendition of the Trapezoid Cut is a fascinating play that takes the classic and modern together and gaining popularity as a side stone combination. Below are some of the center stones it’s often used with, from the beloved Princess Cut, to Pear and Cushion.

Frequently Asked Questions About Trapezoid Side Stones
What is a brilliant cut trapezoid?
It is a trapezoid side stone faceted for sparkle rather than cut in steps. It has the same four-sided outline, with two parallel edges of different lengths, but the faceting returns light like a round or oval. This makes it the trapezoid to use when the center stone is a brilliant.
Which center stones does a brilliant trapezoid pair with?
Round, oval, cushion, and pear centers, where the sparkle matches. The brilliant faceting lets the side stones keep pace with a lively center stone rather than sitting flat beside it. For emerald and Asscher centers, the step cut trapezoid is the correct partner instead.
What is the difference between the brilliant and step cut trapezoid?
Only the faceting, not the outline. The brilliant version sparkles and belongs beside brilliant centers. The step cut has a calm, glassy surface and belongs beside step-cut centers. Choosing the wrong one is the most common mistake with trapezoids, because the shapes look identical loose but read very differently once set beside the center stone.
Do brilliant trapezoids work in a channel or bar setting?
They can, though the trapezoid outline is more often used as a distinct side stone in a three stone ring than as a repeating channel stone. In a bar setting the parallel edges sit flush against the metal, which suits the shape. The sparkle holds up better than a step cut would in a setting that limits light.
Why choose a trapezoid over a half moon as a side stone?
A trapezoid has straight edges and a geometric feel, while a half moon has a curve and a softer feel. Against a square or rectangular center stone the trapezoid's straight lines echo the center, whereas a half moon's curve can look at odds with it. The choice comes down to whether the center stone is angular or rounded.
Sizing, cutting style and the center stones this shape suits are covered in our guide to choosing side stones.
