Is a 2ct diamond ring very big?

A 2 carat engagement ring is big - and well above the average diamond size in the UK. While 2ct is very much on the larger side of engagement rings, it is still a lovely, demure size that won’t look overly flashy. A 2ct diamond ring is a great option for couples with a healthy budget, looking for an eye catching ring.

How common are 2 carat engagement rings?

Around 8% of engagement rings feature a 2ct diamond. It isn’t exactly common to see people wearing 2 carat engagement rings - the average diamond size is much closer to 1 carat. That said, lab diamonds are becoming far more popular - the lower cost per carat means people can get a much larger diamond for their money. Because of this, a 2ct diamond ring is now not quite as rare as it once was.

How big is a 2ct round diamond in mm?

A round 2ct diamond measures around 8.2mm in length. This can vary a little, depending on the cut ratios and symmetry of the diamond. Elongated shapes like ovals will have a bigger surface spread, so can look considerably larger.

How big is a 2ct oval diamond in mm?

An oval 2ct diamond measures around 10mm in length. This will vary from diamond to diamond - and you’ll find that some are shorter and more rounded, with others are longer and thinner. Typically, a 2ct oval diamond appears about 2mm bigger than a round diamond, as the carat weight is spread over a larger surface area.
