The step-cut trapezoids are usually seen next to emerald or Asscher cut center stones. The rectangular emerald shape is ideal for step-cut trapezoid diamonds because it is long enough to accommodate a nice sized side stone between its cut corners.


Trapezoids, also known as trapeze-cut diamonds, are a versatile side stones shape because they can be used with many center diamond shapes. The term trapeze is probably derived from the flying trapeze made famous in the circus. The trapeze cut diamonds were traditionally step-cut but in recent years the brilliant cut trapeze has gained popularity due to the increased demand for radiants and princess cut diamonds.

 Marquise with Trapezoids Diamond Rings

Many diamond ring shoppers are finding the trapezoid cut diamonds makes a great alternative to the trillion or baguettes that are often seen in jewelry store rings. The bigger surface area of the trapezoid adds more sparkle on the finger than the baguette. Many diamond ring buyers find the more sophsicated style of the trapezoid not only looks classy but makes for a more comfortable side stone than the trillion. The short end of the trapezoid does not extend down between the fingers like the trillion often does.

 Crescent Trapezoid Cut Diamonds

One of the newest version of the trapezoid is the crescent trapezoid that has a curved edge on the long end of the trapezoid. These curved edge works well with the curved sides of shapes like the cushion, oval, marquise, or round. It takes a very skilled setter to properly set crescent trapezoids because of their shape and delicate curved points.

 Trapezoid Cut Diamonds

The determine the appropriate size of trapezoid-cut diamonds for a particular ring, it is necessary to know the measurements of the center stone first. If the center stone is a cut-cornered shape like the radiant, emerald, or Asscher, the distance between the cut-corners is critical because the long end of the trapezoid should be equal to or less than that distance. The relative size of the trapezoid side diamonds is a personal preference based on what style of ring is desired. Trapezoids come in a wide variety of sizes and shapes for custom rings that work with many sizes and shapes of diamonds and fingers.

Celebrities have also taken notice of the trapezoid cut diamonds. The over six carat pink diamond engagement ring given to Jennifer Lopez by one-time fiancé Ben Affleck was set in a ring with two trapezoid cut white diamonds as side stones.
