The Cushion Cut Edit

A cushion lab grown diamond ring centres on a real, lab-grown diamond cut in the cushion shape — a square-to-rectangular outline with softly rounded corners, set in a fine band.

The Satéur Aurous Gold Destinée Diamond Ring™ anchors this edit: a real, IGI-certified lab-grown diamond for a fraction of the mined price, cut in the soft, pillow-shaped cushion outline and finished to read far above its cost. Every ring is made-to-order, carried by the Satéur diamond-look guarantee, and shipped worldwide in the signature Maison box with lifetime Satéur Care. The cushion is the cut for couples who want a romantic, slightly vintage silhouette with broad, glowing brilliance.

Each centre stone is a genuine lab-grown diamond — grown, not mined — set into solid 18K gold. The metal is the real thing throughout: 18K gold, hallmarked and built to last, never plated or filled. A mined cushion diamond of comparable grade is a five-figure proposition; the same diamond grown in a lab provides the identical material for a fraction of the spend, which is the whole logic of the category.

It is a real diamond, so it carries the hardness diamond is famous for — Mohs 10, the highest there is — and stands up to daily wear for life. Stones are selected colourless in the D–E range, cut to Excellent and graded VS for clarity, the combination that gives a cushion its soft yet bright, watery return of light across the open table. Each centre diamond arrives with IGI certification confirming the grade.

The edit moves across cushion-cut designs in every register — solitaires that let the pillow shape stand alone, halo and three-stone settings that widen its presence, and bands ranging from crisp white gold to warm yellow gold tones. You can customise the setting style and metal across the range, with each ring built to seat a cushion lab grown diamond securely for everyday life. The grid below shows every piece.

Questions

Cushion Lab Grown Diamond Ring, answered.

What is a cushion lab grown diamond ring?+

It is a ring built around a real, lab-grown diamond cut in the cushion shape — a square-to-rectangular outline with gently rounded corners — set into a fine band. The diamond is a genuine diamond grown in a laboratory rather than mined, typically held in solid 18K gold.

What is a cushion cut diamond?+

A cushion cut diamond has a square or slightly rectangular outline with soft, rounded corners, resembling a pillow. Its larger facets and open table give it a soft, glowing brilliance with a touch of vintage character that has made it a long-standing favourite for engagement rings.

How do lab grown and mined diamonds differ in appearance?+

They do not differ. A lab-grown diamond is the same material as a mined diamond, so a cushion stone of matching colour, clarity and cut looks identical whichever way it was formed — the same fire, brightness and depth of light return.

Can I customize the band metal and setting style?+

Yes. Across the cushion edit you can choose solitaire, halo or three-stone settings and select a band in white gold or warm yellow gold tones, all in solid 18K gold, so the ring suits your taste and how you wear it.

What colour and clarity grades does Satéur offer?+

Satéur lab-grown diamonds are selected in the colourless D–E colour range with VS clarity and Excellent cut grades. This combination keeps a cushion stone bright, white and clean to the eye, and the grade is documented on its IGI certificate.

How should I care for a lab grown diamond ring?+

Care for it as you would any diamond ring: clean it periodically with warm water and a soft brush, and have the setting checked occasionally. With Mohs 10 hardness, the diamond itself is built to withstand a lifetime of daily wear, and lifetime Satéur Care is included.
