3 carat square 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 square radiant diamond?
A 3 carat square radiant diamond typically measures about 8.3 x 7.9 mm, based on the stones in our stock today. A round diamond of the same weight measures about 9.2 mm across, so the square 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 square radiant diamond
Every stone here has a length-to-width ratio of 1.08 or under, so it faces up as a square with trimmed corners; the brilliant faceting hides small inclusions well, so VS2 or SI1 is often clean to the eye. 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 square 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 natural diamond is formed over billions of years and each one is rare; many buyers value that origin. A lab grown diamond of the same grades costs far less. Today the lowest priced 3 carat square radiant diamond in our stock is $41,794 natural, against $1,424 lab grown. Compare 3 carat square radiant lab grown diamonds.
Other sizes
Compare square radiant natural 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.
