The 2 Carat Round Edit

A 2 carat round lab grown diamond ring is an engagement ring set with a two-carat, round brilliant diamond created in a laboratory rather than mined from the earth.

The Satéur Royale Diamond Ring™ anchors our 2 carat round collection: a real, IGI-certified lab-grown diamond for a fraction of the mined price, set in solid 18K gold and delivered free, backed by our lifetime guarantee inside the signature Satéur box. Every ring here carries the same promise — the size and presence buyers expect from a two-carat round, without the markup that has defined the diamond aisle for a century. This is the round brilliant, reimagined for the way people actually shop today.

Each ring is set in solid 18K gold — not plating, not a finish, but genuine 18-karat gold worked by hand around the stone. The diamond itself is IGI-certified, the same independent grading standard applied to mined stones, so every carat weight, colour grade and clarity grade is documented and verifiable. What you read on the certificate is what sits on the band.

A lab-grown diamond is a real diamond. It is carbon, crystallised under the same conditions that form a mined diamond, and it measures 10 on the Mohs scale — the hardest natural material known, ready for a lifetime of daily wear. Across this edit, stones grade in the D–E colour range with Excellent cut and VS clarity, which means a near-colourless body, precision faceting that returns light evenly, and inclusions invisible to the eye.

The collection spans the round brilliant in its most enduring forms — classic four-prong solitaires that let the centre stone speak, halo and accent settings that widen the visual footprint, and three-stone designs that frame the round with flanking diamonds. Carat weights center on the two-carat mark, in white and yellow 18K gold, with bands chosen to balance the proportions of a substantial round stone. Whether the priority is a clean solitaire silhouette or a setting that reads larger on the hand, the range covers it. The grid below shows every piece.

Questions

2 Carat Round Lab Grown Diamond Ring, answered.

What is a 2 carat round lab grown diamond ring?+

It is an engagement ring set with a real, two-carat round brilliant diamond grown in a laboratory rather than mined. The stone is chemically and optically a genuine diamond — it simply forms above ground in weeks instead of underground over millennia, which is why it costs a fraction of a comparable mined diamond.

What is a lab-grown diamond and how is it graded?+

A lab-grown diamond is real diamond — crystallised carbon with the same hardness (Mohs 10) and brilliance as a mined diamond. It is graded by the same independent labs, including IGI, on the same four criteria: carat, colour, clarity and cut. Satéur lab diamonds are IGI-certified so every grade is documented.

How does a 2 carat lab-grown diamond compare in size to a mined diamond?+

Identically. Carat is a measure of weight, and a two-carat lab-grown diamond weighs and measures the same as a two-carat mined diamond — roughly 8.1mm in diameter for a round brilliant. The only meaningful difference is price.

What does IGI certification mean for a lab-grown diamond?+

The International Gemological Institute independently grades and documents the diamond's carat, colour, clarity and cut on a certificate that travels with the stone. It is the same verification used for mined diamonds, so you can confirm exactly what you are buying.

Can a 2 carat round lab-grown diamond be set in any metal?+

Our 2 carat round rings are set in solid 18K gold, available in white and yellow gold across the collection. The metal is genuine 18-karat gold worked around the stone, not a plating or finish.

How do lab-grown and mined diamonds differ in price?+

A lab-grown diamond delivers the same look, hardness and IGI-graded quality for a fraction of the mined price. Because the stone is created in weeks rather than extracted through mining, you pay for the diamond itself — not the cost of getting it out of the ground.
