London-based jeweller Queensmith has noted increased client interest in unconventional diamond cuts and warmer colours as couples seek engagement rings that feel more individual.

The jeweller has identified old mine, moval, criss-cut, trapezoid and elongated hexagonal diamonds among the shapes attracting attention, alongside warm and coloured stones.

Laura Suttie, gemmologist and design expert at Queensmith, said antique-style diamonds had risen particularly strongly in popularity following the attention generated by Taylor Swift’s engagement ring. Old mine cuts date largely from the 18th and 19th centuries and were shaped by hand. Their individual proportions, chunkier facets and softer brilliance appeal to clients seeking character rather than the uniform appearance associated with modern brilliant cuts.

Queensmith is also seeing growing interest in movals, a hybrid of marquise and oval shapes. The cut retains the elongated appearance that has made oval diamonds commercially successful while offering a less familiar silhouette. Elongated hexagonal diamonds have also risen in popularity.

Criss-cut diamonds provide another variation on an established category. Developed by cutter Christopher Slowinski in New York during the 1990s, their intersecting facets introduce more light and movement into the clean geometry of a traditional step cut.
