The Round Brilliant Edit

A round lab grown diamond engagement ring is an engagement ring set with a real, lab-created diamond cut in the round brilliant shape — the classic circular outline engineered for maximum light return.

The Satéur Aurous Gold Destinée Diamond Ring™ leads this round brilliant edit: a real, IGI-certified lab-grown diamond for a fraction of the mined price, set in a ring that arrives ready to propose with. Complimentary delivery, a lifetime guarantee, and the signature Satéur box come with every piece, so the diamond engagement ring you choose lands as a complete moment, not a loose stone. The round brilliant is the most chosen shape in the world for a reason — it gives back the most light of any cut.

Each band is crafted in solid 18K gold — white, yellow, or rose — the precious metal that fine jewellery has always been built on, and every centre stone is independently certified by IGI. Solid gold is not a coating; it runs through the entire band, holding its colour and structure through a lifetime of daily wear. That is the foundation every round lab grown diamond in this collection is set into.

The centre is a genuine diamond, not a substitute. Lab-grown diamonds carry the identical crystal structure and the full Mohs 10 hardness of mined diamonds, and the stones here are graded in the D–E colour range with Excellent cut and VS clarity. In a round brilliant, that Excellent cut grade is what unlocks the shape's signature fire and scintillation — the bright flashes of white and coloured light as the hand moves.

This round lab grown diamond engagement ring collection runs from the solitaire to the halo, from delicate pavé bands to substantial cathedral settings, in white gold and yellow gold across a range of carat weights. Every diamond engagement ring is built on the same round brilliant centre and graded to the same standard, with the band style and the gold colour defining the look. Solitaire, three-stone, and pavé engagement rings all appear in the range, each priced against the value of a comparable mined diamond. The grid below shows every piece.

Questions

Round Lab Grown Diamond Engagement Ring, answered.

What is a round lab grown diamond engagement ring?+

It is an engagement ring set with a real, lab-created diamond cut in the round brilliant shape. The round brilliant has 57 to 58 facets arranged to maximise light return, and the diamond itself is grown in a laboratory — a genuine diamond with the same crystal structure and hardness as a mined stone, offered for a fraction of the mined price.

What is the difference between a lab grown diamond and a mined diamond?+

The only meaningful differences are origin and price. A lab grown diamond is created in a controlled laboratory rather than extracted from the earth, but it has the identical crystal structure, the same Mohs 10 hardness, and the same optical properties as a mined diamond. Both are real diamonds; the lab grown stone simply costs far less.

How is a lab grown diamond graded and certified?+

Lab grown diamonds are graded on the same four criteria as mined diamonds — carat, colour, cut, and clarity — and certified by independent gemological laboratories. Every centre diamond in this collection is independently certified by IGI, with the grading documented on the accompanying certificate.

Can I customize the band with a lab grown round diamond?+

Yes. The collection offers round lab grown diamonds across a range of band styles and gold colours, including solid 18K white and yellow gold solitaire, pavé, halo, and three-stone settings. Browse the grid to find the band that frames your round brilliant the way you want.

What colour and clarity options are available for round lab diamonds?+

The round lab grown diamonds in this edit are selected in the D–E colour range — the near-colourless top of the scale — with VS clarity, meaning inclusions are very slight and invisible to the naked eye. Combined with an Excellent cut grade, this produces the bright, clean brilliance the round shape is known for.

How durable is a lab grown diamond for daily wear in an engagement ring?+

Extremely durable. Lab grown diamonds rate a perfect 10 on the Mohs hardness scale, the same as mined diamonds and the hardest of any gem material. That makes them ideal for an engagement ring worn every day — the stone resists scratching and holds its brilliance for a lifetime, especially set in solid 18K gold.
