3 carat heart shaped 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 heart shaped diamond?
A 3 carat heart shaped diamond typically measures about 9.9 x 8.7 mm, based on the stones in our stock today. A round diamond of the same weight measures about 9.2 mm across, so the heart shaped shows more surface from above and looks larger. Carat measures weight, not size, so cut and proportions affect how big a stone looks.
Choosing a 3 carat heart shaped diamond
Look for even lobes, a clear cleft and a straight, centred point; a ratio of 0.90 to 1.10 gives a balanced heart. 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 heart shaped 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 heart shaped diamond in our stock is $19,660 natural, against $1,235 lab grown. Compare 3 carat heart shaped lab grown diamonds.
Other sizes
Compare heart shaped natural diamonds at 1 carat, 1.5 carat, 2 carat or 5 carat.

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.
