The Marquise Lab Diamond Edit

A marquise lab grown diamond ring is a ring set with a real, lab-grown diamond cut in the marquise shape — an elongated oval tapering to a point at each end — created in a controlled environment with the identical optical and physical properties of a mined diamond.

The Satéur Aurous Gold Raffiné Diamond Ring™ leads this edit: a real, IGI-certified lab-grown diamond for a fraction of the mined price, in the unmistakable marquise silhouette. Every ring in the collection sets a genuine lab-grown diamond in solid gold, and every order arrives with complimentary worldwide delivery, our lifetime guarantee, and the signature Satéur presentation box — the same care a far more expensive stone would receive.

The foundation is solid 18K gold, offered in white, yellow and gold tones across the range — real precious metal throughout, never plating and never a coloured finish. The centre stone is an independently graded, IGI-certified lab-grown diamond, so the cut, carat and grade on the page are the verified specifications on your hand.

A marquise lab grown diamond is, by every measurable standard, a real diamond. It scores a perfect 10 on the Mohs hardness scale, falls in the D–E colour range for a clean colourless white, is finished to Excellent cut standards so the long facets throw maximum light, and carries VS clarity for an eye-clean appearance. The marquise shape also wears larger than its carat weight, since the elongated outline covers more of the finger and draws the eye along its full length.

The collection spans a range of marquise engagement rings and dress rings, from solitaire settings that let the long diamond stand alone to detailed bands with side stones and pavé shoulders. You will find different carat weights, white gold and warm gold metals, and settings tuned to flatter the marquise outline — each a distinct reading of the same idea. Select the cut, carat and metal that suit you; the grid below shows every piece, with full details and price on each.

Questions

Marquise Lab Grown Diamond Ring, answered.

What is a marquise lab grown diamond?+

It is a real, lab-grown diamond cut in the marquise shape — an elongated oval that tapers to a point at both ends. Grown in a controlled environment, it has the same hardness, brilliance and chemistry as a mined diamond, and the marquise cut makes it appear larger than its carat weight.

How does a marquise cut differ from round or oval cuts?+

A marquise is longer and narrower than a round or oval, with two pointed ends rather than a continuous curve. That elongated outline covers more finger surface, so it looks bigger for the same carat weight and lengthens the appearance of the hand, while still returning brilliant light through its faceting.

Are lab grown diamonds real diamonds?+

Yes. A lab grown diamond is a genuine diamond with the same optical, physical and chemical properties as a mined one — it simply forms in a controlled environment rather than underground. It rates a perfect 10 on the Mohs scale and is sold as a real, IGI-certified diamond.

What colour and clarity grades does Satéur offer in lab diamonds?+

Satéur lab diamonds are graded in the D–E colour range — the top of the colourless scale — and at VS clarity, meaning any inclusions are not visible to the naked eye. Stones are cut to Excellent proportions, so every ring reads as a clean, bright, eye-clean diamond.

How is a lab diamond certified and graded?+

Each Satéur lab diamond is independently assessed and IGI-certified, graded on the same four criteria as any diamond — cut, colour, clarity and carat weight. The certificate confirms the verified specifications listed on the product page, so what you read is what you receive.

Can I customise a marquise lab diamond ring with different metals and settings?+

The collection offers the marquise across several metals and settings — solid 18K white gold, yellow gold and gold tones, in solitaire and accented designs. Browse the grid to choose the metal, carat and setting that suit you, with full details on each product page.
