Choosing your lab grown diamond engagement ring

Understand the diamond at the centre

A lab grown diamond is a diamond grown in a controlled environment, with the same essential chemical composition and crystal structure as a natural diamond. It is not moissanite or another diamond simulant. Laboratory-grown origin does not make every diamond identical: compare the individual stone's appearance and report alongside its setting.

Find your preferred shape and setting

Round lab diamond rings offer a balanced outline, while oval lab diamond rings introduce softly elongated curves. For straighter lines and step-cut facets, explore emerald-cut lab diamond rings; for a longer outline with rounded corners, compare elongated cushion lab diamond rings.

A lab diamond solitaire keeps the centre in focus. Lab diamond halo rings add a visible frame, while a hidden halo introduces detail beneath the centre. Shoulder-set diamonds and trilogy designs create different compositions. Look at the full setting from above and from the side.

Compare carat weight, appearance and reports

Carat measures weight, not visible size. Compare the diamond's length and width in millimetres, its proportions and its appearance in photographs or video. More weight alone does not guarantee more sparkle, and a clarity grade cannot by itself establish whether inclusions will be visible to you.

Read the actual document for your chosen diamond. Check the issuing laboratory, report number, date, dimensions and any disclosed growth or treatment information. IGI reports and GIA assessments can use different terminology, so do not assume every document follows the same format. Our lab grown diamond guide provides a fuller introduction.

Choose the metal and plan the complete ring

Platinum and white gold lab diamond rings provide a pale frame; yellow and rose gold bring warmer tones. Compare the band width, claws and setting height, then check how your preferred wedding band sits alongside the design.

Compare current complete-ring prices with the same centre specification, metal and setting. Confirm ring size, the options available for your chosen design and expected timing before ordering. For a different design direction, explore our bespoke ring service, or arrange a consultation at our London showroom or Manchester showroom.

Lab grown diamond ring questions

Are lab grown diamonds real diamonds?

Yes. They are diamonds grown in a laboratory rather than formed naturally within the earth. They share the same essential composition and crystal structure as natural diamonds, while their growth history and identifying features differ. Moissanite is a different gemstone, not another name for lab grown diamond.

What affects the price of a lab grown diamond engagement ring?

The selected diamond's specifications, precious metal, setting and accent stones all affect the complete price. Compare current prices for like-for-like configurations and confirm what is included. A general saving percentage is not a quotation for your chosen ring.

Will two diamonds of the same carat weight look the same size?

No. Shape and cutting proportions affect length, width and depth. Use millimetre measurements to compare the visible outline, then consider the band and setting around it. A halo can widen the finished ring without changing the centre diamond's weight.

Which report accompanies my selected diamond?

Check the individual product and ask our team to confirm the laboratory and document supplied for your selected centre stone. Report formats vary by laboratory, service and issue date. Read centre and accent-stone specifications separately rather than assuming every stone uses the same reporting arrangement.

Where can I find coloured lab grown diamond rings?

This collection focuses on the classic colourless diamond appearance. For pink, blue, green or yellow centres, explore our coloured lab grown diamond rings. Colour and laboratory-grown origin describe different aspects of the diamond.
