Square radiant natural diamonds: what to look for
Every stone here has a length-to-width ratio of 1.08 or under, so it faces up as a square with trimmed corners; the brilliant faceting hides small inclusions well, so VS2 or SI1 is often clean to the eye. Our square radiant diamond guide covers the shape in more detail.
Square radiant diamond sizes and prices
Carat measures weight, not size. These are the typical measurements and lowest prices of the square radiant natural diamonds in our stock today, by carat size:
| Carat | Typical size | Available | From |
|---|---|---|---|
| 1 carat | 5.6 mm | 289 | £952 |
| 1.5 carat | 6.4 mm | 92 | £3,168 |
| 2 carat | 7.1 x 6.9 mm | 36 | £4,984 |
| 3 carat | 8.3 x 7.9 mm | 24 | £21,454 |
| 5 carat | 9.6 x 9.3 mm | 19 | £38,546 |
Square radiant natural diamond prices
Today our square radiant natural diamonds range from £309 to £241,603, across 831 stones. Carat weight makes the biggest difference, followed by colour, clarity and cut. Prices step up at the whole and half carat marks, so a stone just over 1.00, 1.50 or 2.00 carats gives the size for the smallest premium.
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. From one carat up, our lowest priced square radiant diamond today is £952 natural, against £227 lab grown. Compare square radiant lab grown diamonds.
Choosing colour and clarity
Up to about 1.5 carats, G or H colour and VS2 or SI1 clarity usually look white and clean to the eye. From 2 carats colour and inclusions are easier to see, so G or better and VS2 or better are worth considering.
Setting your diamond
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.

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.
