Square cushion 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; the photo shows whether it has classic broad facets or a busier crushed-ice sparkle, which the certificate does not grade. Our square cushion diamond guide covers the shape in more detail.
Square cushion diamond sizes and prices
Carat measures weight, not size. These are the typical measurements and lowest prices of the square cushion natural diamonds in our stock today, by carat size:
| Carat | Typical size | Available | From |
|---|---|---|---|
| 1 carat | 5.7 mm | 3,263 | $1,007 |
| 1.5 carat | 6.6 x 6.4 mm | 1,532 | $2,410 |
| 2 carat | 7.2 x 7.0 mm | 840 | $5,265 |
| 3 carat | 8.3 x 8.0 mm | 149 | $17,033 |
| 5 carat | 9.8 x 9.4 mm | 70 | $46,001 |
Square cushion natural diamond prices
Today our square cushion natural diamonds range from $398 to $1,063,094, across 8,541 stones. Carat weight makes the biggest difference, followed by color, 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 cushion diamond today is $1,007 natural, against $307 lab grown. Compare square cushion lab grown diamonds.
Choosing color and clarity
Up to about 1.5 carats, G or H color and VS2 or SI1 clarity usually look white and clean to the eye. From 2 carats color 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.
