3 carat 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 diamond in each shape?
Carat measures weight, not size, so the same carat weight looks different in each shape. These are the typical measurements of the 3 carat natural diamonds in our stock today:
| Shape | Typical size | Available | From |
|---|---|---|---|
| Round | 9.2 mm | 2,340 | $19,953 |
| Oval | 11.3 x 8.0 mm | 854 | $15,882 |
| Cushion | 9.4 x 7.5 mm | 846 | $19,565 |
| Square cushion | 8.3 x 8.0 mm | 141 | $24,109 |
| Elongated cushion | 9.7 x 7.4 mm | 636 | $19,565 |
| Emerald cut | 9.8 x 6.9 mm | 698 | $19,415 |
| Princess cut | 8.0 x 7.8 mm | 196 | $20,510 |
| Radiant | 9.5 x 7.2 mm | 393 | $22,995 |
| Square radiant | 8.3 x 7.9 mm | 26 | $40,648 |
| Elongated radiant | 9.6 x 7.2 mm | 361 | $22,995 |
| Asscher cut | 7.9 mm | 153 | $25,867 |
| Marquise | 14.7 x 7.4 mm | 253 | $16,310 |
| Heart shaped | 9.9 x 8.7 mm | 366 | $19,120 |
| Pear shaped | 12.6 x 7.9 mm | 744 | $15,552 |
Choosing a 3 carat diamond
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. Use the shape filter above, or go straight to round, oval, cushion, square cushion, elongated cushion, emerald cut, princess cut, radiant, square radiant, elongated radiant, Asscher cut, marquise, heart shaped or pear shaped.
3 carat 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 diamond in our stock is $15,552 natural, against $954 lab grown. Compare 3 carat lab grown diamonds.
Other sizes
Compare 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.
