The Oval Statement Edit

A 3 carat oval lab grown diamond ring is an engagement ring set with an elongated, oval-shaped diamond grown in a laboratory, weighing three carats and graded to the same standards as a mined stone.

The Satéur Aurous Gold Destinée Diamond Ring™ opens this collection of three carat oval engagement rings — a real, IGI-certified lab-grown diamond for a fraction of the mined price. Every ring ships with free delivery, a lifetime guarantee, and the signature Satéur box, so a stone of this scale arrives feeling exactly as significant as it looks.

Each ring is set in solid 18K gold rather than plating, with the band engineered to carry a larger stone for everyday wear. The centre is an IGI-certified lab-grown diamond, grown with the same carbon structure as a mined diamond and documented by the same independent laboratory. At three carats, solid metal and genuine certification are what let a stone this size sit on the hand at a price mined diamonds cannot come close to.

The diamond is a real diamond — Mohs 10, the hardest material there is — graded to D–E colour, Excellent cut, and VS clarity. Across an oval outline at three carats, that near-colourless brilliance becomes a true statement on the finger, returning the same flawless, icy light a mined stone gives, with the compromise sitting only in the price.

The collection spans the oval cut and the round brilliant, the clean solitaire and the haloed setting, length-to-width ratios from rounded to elongated, and metals from bright 18K white gold to warm 14K and 18K yellow gold. Whatever band and proportion you choose, every three carat lab grown diamond ring here carries the same certification and the same value. The grid below shows every piece.

Questions

3 Carat Oval Lab Grown Diamond Ring, answered.

What is a 3 carat oval lab grown diamond ring?+

It is a statement engagement ring set with an oval-shaped diamond that weighs three carats and was grown in a laboratory. The oval is an elongated brilliant cut, and the lab-grown diamond is a real diamond with the same carbon structure, Mohs 10 hardness, and IGI certification as a mined stone.

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

They do not differ in either. A lab-grown diamond is the same material as a mined diamond — Mohs 10, the hardest there is — so it is just as durable, and it has the same fire and brilliance because its crystal structure is identical. The difference is origin and price, not how the stone wears or looks.

What carat weight and cut options are available for oval lab diamond rings?+

This collection centres on three carat oval stones, and the wider range includes other carat weights and the round brilliant cut as well. Every stone is cut to an Excellent grade for strong light return, and the product pages list the specific weight for each ring.

Can I request a custom setting or metal choice for my ring?+

Many designs are offered in more than one metal — solid 18K white gold, plus 14K and 18K yellow gold on selected styles — and in different settings such as solitaire or halo. Check the individual product page for the options available on each ring.

What certifications do your lab grown diamonds carry?+

Each lab-grown diamond is independently graded and certified by IGI. The certificate documents the stone's carat, colour, clarity, and cut, giving you third-party verification of its quality and authenticity.

What is the colour and clarity range of your lab diamonds?+

Our lab-grown diamonds are graded to D–E colour, the near-colourless top of the scale, and VS clarity, with an Excellent cut. These grades are recorded on the IGI certificate for the specific stone in your ring.
