What is a trapeze cut gemstone?

Definition
A trapeze cut is a step-cut gemstone with four sides where the top and bottom edges are parallel but the two longer sides angle inward or outward, forming a trapezoid silhouette with a flat top. It is essentially a truncated triangle, and it should not be confused with a true triangular cut. Trapeze-cut diamonds are used as architectural side stones in fine jewellery, particularly flanking emerald or asscher-cut centre stones, where their clean geometric lines complement the centre stone without competing with it.
Frequently asked questions
- What is the difference between a trapeze cut and a trapezoid cut?
- The two terms are used interchangeably in many jewellery contexts and describe the same basic four-sided, flat-topped step-cut shape. Some makers use trapeze for the angled, triangular-derived form and trapezoid for a more rectangular version with two parallel sides, but there is no universal standard distinction in the trade.
- What rings commonly use trapeze-cut side stones?
- Trapeze-cut stones appear most often in Art Deco revival and contemporary architectural jewellery, paired with step-cut centres like the emerald cut or asscher cut. Their geometric precision suits designs where clean lines and a structured aesthetic are the goal rather than the all-over sparkle of brilliant-cut accents.
- Are trapeze-cut diamonds brilliant or step-cut?
- They are step-cut, meaning the facets run in parallel rows across the stone rather than in the triangular arrangements of a brilliant cut. Step cuts have fewer facets and produce a quieter, more reflective quality than brilliant cuts, letting the colour of the stone and the geometry of the shape read clearly.
