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 lab grown diamonds in our stock today:
| Shape | Typical size | Available | From |
|---|---|---|---|
| Round | 9.3 mm | 19,352 | $1,108 |
| Oval | 11.8 x 8.0 mm | 15,600 | $1,108 |
| Cushion | 9.3 x 7.8 mm | 8,215 | $1,009 |
| Square cushion | 8.4 x 8.2 mm | 3,044 | $1,114 |
| Elongated cushion | 10.0 x 7.5 mm | 5,005 | $1,009 |
| Emerald cut | 9.8 x 6.8 mm | 6,957 | $981 |
| Princess cut | 7.9 mm | 5,237 | $1,164 |
| Radiant | 10.1 x 7.2 mm | 6,598 | $1,087 |
| Square radiant | 8.1 x 7.9 mm | 341 | $1,424 |
| Elongated radiant | 10.2 x 7.1 mm | 6,252 | $1,087 |
| Asscher cut | 8.0 mm | 1,360 | $1,065 |
| Marquise | 14.9 x 7.5 mm | 6,144 | $1,087 |
| Heart shaped | 10.0 x 8.9 mm | 1,435 | $1,235 |
| Pear shaped | 12.8 x 8.0 mm | 6,717 | $1,164 |

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 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 diamond in our stock is $981 lab grown, against $15,989 natural. Compare 3 carat natural diamonds.
Other sizes
Compare lab grown 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.
