1.5 carat diamonds: what to expect
A 1.5 carat diamond is a confident step up from one carat, large enough to read clearly as a statement stone. It looks about 14% wider than a 1 carat stone of the same shape and shows around 31% more surface from above, even though it weighs half as much again.
How big is a 1.5 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 1.5 carat lab grown diamonds in our stock today:
| Shape | Typical size | Available | From |
|---|---|---|---|
| Round | 7.4 mm | 51,761 | $428 |
| Oval | 9.3 x 6.4 mm | 19,991 | $414 |
| Cushion | 7.5 x 6.2 mm | 10,552 | $400 |
| Square cushion | 6.7 x 6.5 mm | 4,177 | $418 |
| Elongated cushion | 8.1 x 5.9 mm | 6,221 | $400 |
| Emerald cut | 7.8 x 5.4 mm | 13,777 | $385 |
| Princess cut | 6.3 mm | 8,617 | $424 |
| Radiant | 8.1 x 5.7 mm | 9,884 | $390 |
| Square radiant | 6.5 x 6.3 mm | 304 | $404 |
| Elongated radiant | 8.1 x 5.7 mm | 9,547 | $390 |
| Asscher cut | 6.4 mm | 3,755 | $443 |
| Marquise | 11.8 x 6.0 mm | 7,873 | $452 |
| Heart shaped | 8.0 x 7.1 mm | 5,193 | $481 |
| Pear shaped | 10.2 x 6.4 mm | 13,581 | $409 |
Choosing a 1.5 carat diamond

1.5 carat diamond prices
Prices step up again at 1.50 carats, so a stone between 1.50 and 1.60 gives the look of a "carat and a half" for the least premium.
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 1.5 carat diamond in our stock is $385 lab grown, against $2,256 natural. Compare 1.5 carat natural diamonds.
Other sizes
Compare lab grown diamonds at 1 carat, 2 carat, 3 carat or 5 carat.
