An elongated cushion cut is a modified cushion shape with a longer length than width.

It keeps the soft, rounded corners of a traditional cushion cut while extending the outline for a slimmer, more elegant profile. The shape offers strong finger coverage and a balanced look that sits between classic and modern.

The facet pattern delivers a mix of soft brilliance and depth rather than sharp flashes, which gives the stone a refined, steady sparkle.

KEY CHARACTERISTICS

• Rectangular cushion outline with rounded corners
• Longer length creates a slimming effect on the finger
• Larger face-up appearance compared to standard cushion cuts
• Balanced sparkle with visible depth
• Works well with halos, pavé bands, and clean solitaire settings

An elongated cushion cut suits you if you want a shape that feels classic but more refined and elongated than a traditional cushion.
