2 Carat Lab Grown Round Cut Diamonds

Many well-proportioned 2 carat lab grown round cut diamonds measure approximately 8.1–8.2mm across. Always check the individual grading report because measurements differ from stone to stone.

A 2 carat lab grown round cut diamond provides a clear increase in face-up coverage over 1ct, but it does not appear twice as wide because carat measures weight rather than diameter.

The larger viewing area can make some inclusions easier to detect. Reviewing their location and appearance can therefore be more useful than selecting a 2ct lab grown round cut diamond purely by clarity grade.

Cut should be one of the main considerations because it influences light return and the way the stone presents from above. Strong proportions can also help the carat weight translate effectively into visible size.

Yes, to a degree. We typically move to sturdier, fewer pronged settings at this weight, rather than the finer decorative prongs sometimes used on smaller diamonds.

The grading process is identical. IGI and GIA apply the same 4Cs criteria at every weight, though larger stones receive additional scrutiny under magnification simply because there is more surface area to assess.

Some upgrade schemes are available. We are happy to talk through your options during a consultation, as terms depend on the original purchase and the condition of the stone.

Around 5 to 6 weeks for a fully bespoke design, though this can vary with the complexity of the setting. We will confirm an exact date once your design is agreed.

We generally suggest F to G colour and VS1 clarity if your budget allows, since a larger table face makes both colour tint and inclusions marginally easier to notice than at 1 carat. G to H colour and VS2 clarity remain excellent choices for most settings.

 Yes. Our Hatton Garden showroom regularly has both available to view side by side, which is often the clearest way to decide.
