The princess cut diamond
The princess cut is a square brilliant: crisp straight sides, sharp corners and a lively, criss-cross sparkle. It is the most popular fancy shape, and because more of the rough crystal is kept when it is cut, a princess often costs less than a round of the same weight. With a princess diamond, a solitaire shows off the full outline of the stone.
Why a solitaire?
A solitaire is the purest engagement ring: one diamond on a plain band, with nothing to compete with the stone. It never dates, lets more light into the diamond than any other setting, and sits easily beside almost any wedding ring.
Why 18ct yellow gold?
18ct yellow gold is 75% pure gold, with the deep, warm colour people picture when they think of a gold ring. It is not plated, so the colour never fades. Some of our yellow gold designs hold the diamond in a white platinum head, so the stone looks as white as possible while the band stays golden. Yellow gold also flatters a slightly warmer diamond, so a stone in the H to J colour range can look just as good as a pricier, whiter one. For a lower price, see our 9ct yellow gold engagement rings.
Choosing your princess diamond
Look for a length-to-width ratio between 1.00 and 1.05 for a true square. The corners are the most delicate part of a princess cut, so each one is held by its own claw. A G to H colour and SI1 clarity give a clean, bright look for the money.
Choose your own diamond
Every ring is set with a centre diamond you choose yourself, natural or lab-grown, from our live stock. Each stone has its grading report, and the ring page shows the finished price before you buy.

Frequently Asked Questions
The stone itself is as hard as any diamond, but its sharp corners can chip if knocked. That is why every corner on our princess settings is protected by its own claw.
Yes. A plain wedding band sits neatly beside most solitaires, and if the setting sits low, a shaped band fits around it. Our wedding ring designer makes matching plain bands.
Yellow gold reflects a little warmth into the diamond, so a near-colourless stone in the H to J range looks just as good as a whiter, more expensive one. If you want an icy white stone, choose a design with a platinum head.
