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 | 53,130 | £310 |
| Oval | 9.3 x 6.4 mm | 20,588 | £302 |
| Cushion | 7.4 x 6.2 mm | 10,909 | £295 |
| Square cushion | 6.7 x 6.5 mm | 4,383 | £310 |
| Elongated cushion | 8.1 x 5.9 mm | 6,344 | £295 |
| Emerald cut | 7.8 x 5.4 mm | 14,029 | £281 |
| Princess cut | 6.3 mm | 8,841 | £302 |
| Radiant | 8.0 x 5.7 mm | 9,955 | £288 |
| Square radiant | 6.5 x 6.3 mm | 311 | £299 |
| Elongated radiant | 8.1 x 5.7 mm | 9,609 | £288 |
| Asscher cut | 6.4 mm | 3,816 | £324 |
| Marquise | 11.8 x 6.0 mm | 7,989 | £335 |
| Heart shaped | 8.0 x 7.1 mm | 5,425 | £353 |
| Pear shaped | 10.2 x 6.4 mm | 13,791 | £302 |
Choosing a 1.5 carat diamond
Colour and inclusions start to show more at this size, so G or better and VS2 or better are worth considering, particularly in 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.
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 £281 lab grown, against £1,663 natural. Compare 1.5 carat natural diamonds.
Other sizes
Compare lab grown diamonds at 1 carat, 2 carat, 3 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.
Your questions answered
Which diamond shape looks biggest at 1.5 carat?

How much does a 1.5 carat lab grown diamond cost?
Today our 1.5 carat lab grown diamonds range from £281 to £13,356, across 149,050 stones. Colour, clarity, cut and the exact carat weight make the difference.
Should I choose a natural or lab grown 1.5 carat diamond?
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 £281 lab grown, against £1,663 natural. Both are graded on the same 4Cs and come with a certificate.
What colour and clarity should a 1.5 carat diamond be?
