3 carat radiant diamonds: what to expect
A 3 carat diamond is a true statement stone, noticeably larger than most engagement ring diamonds. It looks about 44% wider than a 1 carat stone of the same shape and shows around 108% more surface from above, even though it weighs three times as much.
How big is a 3 carat radiant diamond?
A 3 carat radiant diamond typically measures about 10.1 x 7.2 mm, based on the stones in our stock today. A round diamond of the same weight measures about 9.3 mm across, so the radiant looks a similar size on the hand. Carat measures weight, not size, so cut and proportions affect how big a stone looks.
Choosing a 3 carat radiant diamond
Radiants come square (ratio up to 1.08) or elongated (1.15 and up); the brilliant faceting hides small inclusions well. At three carats colour and clarity are easy to see, so we suggest F or G colour and VS2 or better clarity, with VS1 or better for step cuts.
3 carat radiant diamond prices
Prices rise steeply with weight at this size, so comparing stones across the band, and between natural and lab grown, makes a real difference.
Natural or lab grown?
A lab grown diamond has the same chemistry, hardness and sparkle as a natural diamond, at a fraction of the price, which is why it is a popular way to reach a larger size. Today the lowest priced 3 carat radiant diamond in our stock is $1,073 lab grown, against $23,328 natural. Compare 3 carat radiant natural diamonds.
Other sizes
Compare radiant lab grown diamonds at 1 carat, 1.5 carat, 2 carat or 5 carat.
Setting your diamond
Every diamond here can be set in an engagement ring, pendant or earrings made to order in our Bourton-on-the-Water workshop, hallmarked in the UK. Browse engagement rings or design your own. If the stone you want is not listed, our team can source it for you.
Your questions answered
How big is a 3 carat radiant diamond?

How much does a 3 carat radiant lab grown diamond cost?
Today our 3 carat radiant lab grown diamonds range from $1,073 to $72,550, across 6,581 stones. Colour, clarity, cut and the exact carat weight make the difference.
Should I choose a natural or lab grown 3 carat radiant diamond?
A lab grown diamond has the same chemistry, hardness and sparkle as a natural diamond, at a fraction of the price, which is why it is a popular way to reach a larger size. Today the lowest priced 3 carat radiant diamond in our stock is $1,073 lab grown, against $23,328 natural. Both are graded on the same 4Cs and come with a certificate.
What colour and clarity should a 3 carat radiant diamond be?
At three carats colour and clarity are easy to see, so we suggest F or G colour and VS2 or better clarity, with VS1 or better for step cuts.
