Lab Grown Elongated Cushion Cut Diamonds

It’s a lab grown diamond shaped like a stretched cushion — the soft, rounded corners of a classic cushion cut, pulled into a longer outline that sits closer to an oval or rectangle. It offers a distinctive middle ground between the vintage charm of a cushion and the sleek length of an elongated shape.

Crushed ice faceting gives a sparkling, scintillating look with many small reflections, while chunky facets create bold flashes of light. Elongated cushions can be cut in either style.

They are less common because achieving the perfect elongated proportions requires precision cutting. This makes them highly sought-after for those who want something distinctive.

Yes. The elongated outline covers more finger surface, making the diamond appear bigger than its actual carat weight, especially when compared to square cushions or rounds.

Lab grown diamonds generally cost 30-40% less than natural diamonds of the same carat, cut, colour, and clarity. This price difference lets buyers choose a larger carat weight or higher clarity grade within the same budget.

For a noticeably elongated silhouette while keeping the soft cushion character, a ratio of around 1.15 to 1.30 works well. Below 1.15, the stone looks closer to a traditional square or rounded cushion; above 1.30, it starts resembling an oval.

Solitaire, halo, and three-stone settings all work well. A thin pave or hidden halo setting emphasizes the elongated silhouette, while a classic four-prong solitaire keeps the focus purely on the stone’s shape and length.

To some extent, yes. Its rounded corners and faceting pattern can help mask minor inclusions better than step-cut shapes like emerald or asher, so VS2 clarity often still looks eye-clean.

Check that the length-to-width ratio is even along the stone’s full length, and that the rounded curve at all four corners is symmetrical. Viewing certified images or requesting a video from the retailer helps confirm this before buying.

Yes, most retailers sell loose certified stones so you can choose your own setting and metal separately, or have it custom-set into a ring, pendant, or earrings.
