18ct yellow gold princess cut halo engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The princess cut is a square diamond with pointed corners and a brilliant, criss-cross sparkle. A halo surrounds the centre diamond with a ring of smaller diamonds for extra sparkle and a bigger look.
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. The halo follows the outline of the princess diamond, so the shape reads clearly from across a room.
Why a halo?
A halo frames the centre diamond with a ring of small diamonds. The extra sparkle makes the centre stone look larger, so it is a good way to get a big look for less. Paired with a diamond-set band, it gives the most sparkle of all.
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

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. The ring of small diamonds adds to the spread of the centre stone, so it looks noticeably larger than it would on its own.
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.
Yes. Every ring can be set with a natural or lab-grown diamond from our live stock. Both are real diamonds; lab-grown stones cost less for the same size and grade.
