Buying guide
A trapezoid is a step-cut stone with four sides, wider on the edge that meets the center and narrower on the outer edge. Set beside the center, the pair tapers the eye toward it, so the center looks larger and the ring reads as one clean line. Step cuts flash in broad planes instead of sparkling like brilliant cuts, which gives this trapezoid side stone engagement ring a tailored, architectural look.
Straight-edged centers like emerald, asscher, radiant and princess line up neatly with the flat inner edge of each trapezoid. Round, oval and cushion centers soften that geometry for a more classic feel, while pear, marquise and heart give a bolder outline. The center can also be a fancy color, such as pink, yellow, blue or green, for a more personal ring.
The setting starts under $450, and most versions are about $900. That covers the setting with its lab-grown diamond side stones; the center is priced when you choose it.
