The Round Lab Diamond Edit

A round lab grown diamond ring is a ring set with a round-brilliant-cut laboratory-grown diamond — a real diamond, chemically and optically identical to a mined diamond, independently graded and IGI-certified.

At Satéur, the round lab grown diamond ring is anchored by the Satéur Destinée Diamond Ring™, 18K White Gold, Round Cut and its warm-toned Aurous Gold edition — the brand's signature round-brilliant silhouette in a certified lab-grown diamond. Each centre stone is a real, IGI-certified lab-grown diamond offered for roughly a fraction of the mined-diamond price, with free worldwide delivery, a lifetime guarantee, and the signature Satéur box.

A round lab grown diamond is a genuine diamond grown above ground — identical in optical, physical, and chemical properties to a mined stone, with no difference in appearance. On a one-carat-and-up centre stone an IGI certificate accompanies every diamond, and all settings are built in solid 18K gold: 18K white gold for the brightest diamond presentation and warm 18K yellow gold across the warm-toned editions.

The round brilliant is graded to mined-diamond standards: D–E colour, Excellent cut, and VS clarity, cut to fifty-seven or fifty-eight facets for maximum light return and the highest brilliance of any diamond shape. As a real diamond the stone rates Mohs 10 — the hardest material on the scale — so a round lab diamond ring is built for everyday engagement-ring wear and backed by a lifetime guarantee.

The round cut is the most popular shape for engagement rings, and the collection spans every setting register — solitaire, pavé, three-stone, eternity and tension settings in solid 18K white and yellow gold, from one carat up — with men's fine jewellery styles included for customisation across one round lab grown diamond range. The grid below shows every piece, covering price, carat, cut and metal.

Questions

Round Lab Grown Diamond Rings, answered.

What is a round lab grown diamond ring?+

A round lab grown diamond ring is a ring set with a round-brilliant-cut laboratory-grown diamond — a real diamond, chemically and optically identical to a mined diamond, independently IGI-certified. At Satéur it is set in solid 18K gold, graded D–E colour with an Excellent cut, and offered for a fraction of the mined-diamond price.

What is a lab grown diamond?+

A lab grown diamond is a real diamond grown above ground in a controlled environment rather than mined from the earth. It is chemically, physically, and optically identical to a mined diamond, rates the same Mohs 10 hardness, and is graded by the same IGI process — typically costing a fraction of a comparable mined stone.

How does a round lab diamond compare to a mined diamond in appearance?+

It is identical. A round brilliant lab grown diamond has the same carbon crystal structure, refractive index, fire, and brilliance as a mined round diamond — there is no visible difference. The only meaningful difference is the price, with the certified lab stone costing a fraction of the mined equivalent.

How durable are lab grown diamonds for everyday wear?+

Lab grown diamonds rate Mohs 10 — the highest point on the hardness scale, identical to mined diamonds. They are the most durable material available for an everyday engagement ring and need no special care beyond normal fine jewellery maintenance. Every Satéur ring is backed by a lifetime guarantee.

Can I customise the band on a round lab diamond ring?+

The collection covers the most popular round-cut settings, metals, and band styles in solid 18K white and yellow gold, in stock for immediate dispatch. For bespoke requests such as setting modifications, engraving, or carat adjustments, contact Satéur customer care and we will advise on options and timelines.

What is the price difference between lab and mined diamonds?+

Round lab grown diamonds typically cost 30–50% less than mined diamonds of comparable grade and certification — and Satéur prices its IGI-certified rings to deliver a real diamond for a fraction of the traditional mined price, with the same D–E colour, Excellent cut, and Mohs 10 durability.
