The 1 Carat Edit

A 1 carat round lab grown diamond ring is an engagement ring set with a single round-brilliant lab-grown diamond weighing one carat, the most classic size and shape pairing for a solitaire.

The Satéur Aurous Gold Destinée Diamond Ring™ anchors this edit: a real, IGI-certified lab-grown diamond for a fraction of the mined price, in the size and shape most people picture when they imagine an engagement ring. Every ring ships with complimentary delivery, a lifetime guarantee, and the Satéur box. A one-carat round diamond is the benchmark proposal stone, and here it arrives without the benchmark price.

The setting is solid 18K gold rather than plate, and each diamond is accompanied by an independent IGI grading report. You get a metal that wears for a lifetime and a certificate that confirms the carat and quality of the stone resting in it. The value is in the origin of the diamond, not in any shortcut on the ring.

These are real diamonds, identical in hardness and fire to mined stones, rating 10 on the Mohs scale. We hold to D–E colour, Excellent cut, and VS clarity, the grades that make a round brilliant look bright and clean from across a room. At one carat, cut quality is what makes the stone sparkle, and Excellent cut is the standard here.

The edit centres on the round brilliant shape at the one-carat weight, shown in solitaire and accented settings across white gold and yellow gold, with companion rings stepping up in carat for those who want more presence. Whether you choose a plain round solitaire or a setting with detail at the shoulders, the price stays a fraction of the mined equivalent. The grid below shows every piece.

Questions

1 Carat Round Lab Grown Diamond Ring, answered.

What is a 1 carat round lab grown diamond ring?+

It is an engagement ring set with a single round-brilliant lab-grown diamond weighing one carat. The diamond is a real, IGI-certified diamond identical to a mined stone in chemistry and brilliance, offered at a fraction of the mined price.

How big is a 1 carat round lab grown diamond?+

A 1 carat round brilliant typically measures around 6.4 to 6.5 millimetres across the top, the classic solitaire footprint that reads clearly on the hand. Because the round cut is fully optimised for brilliance, a well-cut one-carat stone looks bright and full at this size.

How much does a 1 carat lab grown diamond cost?+

A 1 carat lab-grown diamond costs a fraction of a mined diamond of the same colour, cut, and clarity. The savings come from how the diamond is created, not from any compromise on the stone, so you get a real, certified one-carat diamond for far less.

Is a 1 carat lab grown diamond a good engagement ring size?+

One carat is the most popular engagement-ring size for good reason: it has clear presence on the hand without being oversized, and it photographs beautifully. With a lab-grown diamond, you can reach this classic size at an accessible price.

What is the difference between 1 carat lab grown and mined diamonds?+

Visually and chemically, there is no difference. Both are real diamonds rating 10 on the Mohs hardness scale and are graded on the same colour, cut, and clarity scales. The lab-grown stone is created rather than mined, which is the only reason its price is lower.

How are 1 carat lab grown diamonds graded?+

They are graded by independent laboratories on carat, colour, cut, and clarity, exactly like mined diamonds. Every Satéur stone is IGI-certified, and we select D–E colour, Excellent cut, and VS clarity so a one-carat round looks bright, white, and clean.
