Why choose a custom elongated cushion cut diamond engagement ring?
Elongated cushion cut diamonds have emerged as the most requested luxury engagement ring shape of the decade.

Our Surat goldsmiths hand-craft custom mountings for elongated cushions — from razor-thin pave bands and compass prongs to delicate hidden halos that elevate the stone's natural profile.
Handcrafted in solid gold or 950 platinum with GIA/IGI certification and direct Surat atelier craftsmanship.
Everything you need to know about custom elongated cushion diamond rings
What is an elongated cushion cut diamond?
An elongated cushion cut diamond is a cushion cut stone with a length-to-width ratio between 1.15 and 1.30 (compared to a standard square cushion ratio of 1.00–1.05). It combines the soft, pillow-like rounded corners of a classic cushion with the slender, finger-lengthening profile of an oval cut.
Why are elongated cushion cut diamonds so popular?
Elongated cushion cut diamonds are currently one of the most requested diamond shapes in luxury bridal jewellery. They provide superior finger coverage compared to square cuts, retain soft rounded corners that do not snag, and emit romantic crushed-ice sparkle.
What ratio is considered ideal for an elongated cushion?
A ratio of 1.15 to 1.25 is considered the sweet spot for an elongated cushion cut diamond — subtle elongation without appearing overly narrow. A ratio of 1.28–1.35 yields a distinctly slender silhouette.
What are the best setting styles for a custom elongated cushion diamond ring?
Ultra-thin pavé bands (1.5mm–1.8mm), hidden halos beneath the central basket, and 4-claw solitaire mountings are the preferred settings for elongated cushions. These settings keep the focus on the stone's slender proportions.
