Square Radiant Cut Diamonds

Square radiant cut diamonds combine trimmed corners and brilliant faceting in a square outline. Every stone below has a length-to-width ratio of 1.08 or under, so it faces up as a square. Buy a loose square radiant diamond on its own, or have it set to order in our workshop.

What is a square radiant cut diamond?
A square radiant has the clean, cut-cornered outline of an Asscher with the lively sparkle of a brilliant cut. It is crisp and modern, and its trimmed corners make it more durable than a princess cut. It is also a favourite for fancy coloured diamonds, because the faceting intensifies colour.
How to choose a square radiant
Reading the ratio
The ratio is the diamond's length divided by its width, from the certificate measurements. A perfect square is 1.00, and up to 1.08 the eye still reads it as square. From 1.15 the length clearly shows, and those stones are in our elongated radiant search. Stones in between appear under all radiant cut diamonds.
Colour and clarity
VS2 or SI1 clarity is usually clean to the eye. G or H colour looks white in platinum or white gold.
Square radiant vs princess and Asscher
A princess cut is also square and brilliant, but has sharp, exposed corners. An Asscher has the same cut corners but step facets and a calmer look. The square radiant sits between them, with strong sparkle and protected corners.
Popular Square Radiant diamond sizes
Most of our customers choose between 1 and 3 carats. Start with one of these sizes, or use the carat filter above for anything else:

Setting your square radiant diamond
A square radiant suits four claws, a halo or a three-stone ring. Every ring is made to order in our Bourton-on-the-Water workshop and hallmarked in the UK. Browse our radiant cut engagement rings, or design your own around the diamond you choose here.
You can also build a ring in 3D with Ring Maker, starting with a radiant cut diamond, or see the shape in radiant cut diamond earrings and radiant cut diamond pendants.
Square Radiant Cut Diamonds: your questions answered
What ratio is a square radiant cut diamond?
1.08 or under. A perfect square is 1.00, and stones up to 1.08 still face up as square.
Is a square radiant the same as a princess cut?
No. Both are square and sparkly, but a radiant has trimmed corners, which make it more durable, while a princess cut has sharp points.
Is a square radiant good for a coloured diamond?
Yes. Radiant faceting intensifies colour, which is why many yellow and pink diamonds are cut this way.
Where can I see slightly elongated radiants?
Stones with a ratio between 1.09 and 1.14 are shown with all radiant cut diamonds, alongside the square and elongated stones.
Can I buy a loose square radiant diamond?
Yes. Every diamond on this page can be bought loose, with its grading certificate: choose Buy the Diamond on the stone you like, and it is usually delivered in 7 to 10 days. Or choose Add Jewellery to have it set in a ring, earrings or a pendant, made to order in our Bourton-on-the-Water workshop and hallmarked in the UK.
