Lab-Grown or Natural Diamond: Which Is Right for Your Ring?

What is a lab-grown diamond?

A lab-grown diamond is a diamond made under controlled conditions rather than formed in the earth. It has the same chemical structure as a natural diamond. The difference is its origin.

A natural diamond forms deep within the earth. If its natural history matters to you, that may be part of what makes the ring special.

Can you see the difference?

Most people cannot tell the origin of a cut diamond by looking at it. Its shape, cut, proportions and setting will have a much greater effect on how the ring looks on your hand. A grading report can identify whether a diamond is natural or lab-grown. Ask about the report for the stone you are considering.

Carati includes your diamond’s grading certificate

Every lab-grown centre diamond we sell at Carati comes with an official report from the Gemological Institute of America (GIA). When you purchase a ring with a lab-grown centre diamond, we include that diamond’s certificate with your purchase so you have a record of the stone you chose.

The GIA report identifies the diamond as lab-grown and documents its assessment. If you’re comparing two stones, ask us to walk you through their reports. We can show you which details matter for the look you want and explain how the centre stone differs from any diamonds in the setting.

How does the price compare?

Lab-grown diamonds often cost less than natural diamonds of a comparable size and quality. Prices change with the individual stone, so we would rather show you two real options than promise a fixed saving. You may prefer a larger lab-grown centre stone, or you may choose a natural stone and keep the setting simple.

Look at the whole ring

The centre stone is only one part of the design. Some rings have small diamonds on the band or around the centre. Those stones may have a different origin from the centre diamond. Before you choose, check the details for every stone in the ring. We can walk you through them in person or by video.

Questions we hear often

Is a lab-grown diamond a real diamond? Yes. It is a diamond with a different origin from a natural diamond.

Will the two look different in a ring? Origin is not usually visible by eye. Compare the individual stones and their grading reports.

Are all the diamonds in a lab-grown centre ring lab-grown? Not necessarily. Ask about the centre and any side stones separately.

Can I choose either type for a custom ring? We can discuss the available stones for your design during a consultation.
