What is an elongated radiant cut diamond?
An elongated radiant is a rectangular diamond with cut corners and brilliant faceting. It has the clean lines of an emerald cut with far more sparkle, looks larger for its weight than a square radiant and lengthens the look of the finger.
How to choose an elongated radiant
Choosing the ratio
The ratio is the diamond's length divided by its width, from the certificate measurements. Between 1.20 and 1.40 gives a classic rectangle; above 1.40 the stone becomes long and slim, a look that suits a bold solitaire. Every stone here is shown with its own photo, because the corners and outline vary from one diamond to the next.
Colour and clarity
The brilliant faceting hides small inclusions well, so VS2 or SI1 is usually clean to the eye. Colour can show slightly at the ends of a long stone, so G or H is a good choice in white metal.
Elongated radiant vs emerald cut and elongated cushion
An emerald cut has the same rectangular outline but step facets and calmer flashes of light. An elongated cushion has softly rounded corners and a vintage feel. The elongated radiant is the brightest and most modern of the three.
Popular Elongated 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 elongated radiant diamond
An elongated radiant suits four claws, a hidden halo or side stones such as tapered baguettes, set north to south or east to west. 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.
Elongated Radiant Cut Diamonds: your questions answered
What ratio is an elongated radiant cut diamond?
1.15 or more. Between 1.20 and 1.40 is the classic rectangle; higher ratios give a longer, slimmer stone.
Is an elongated radiant the same as an emerald cut?
They share an outline, but a radiant has brilliant facets and much more sparkle, while an emerald cut has step facets and long, calm flashes of light.
Does an elongated radiant look bigger than a square radiant?
Yes. Its longer outline shows more of the stone from above, so it looks larger than a square radiant of the same carat weight.
Why does every diamond on this page have a photo?
Elongated radiants vary in outline and corners even at the same ratio, so we only list stones with a real photo, letting you see exactly what you are buying.
Can I buy a loose elongated 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.
