18ct White Gold Princess Cut Solitaire Engagement Rings

18ct white gold princess cut solitaire 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 solitaire holds one diamond on a clean band, so all the attention goes to the stone.

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 white gold?

18ct white gold is 75% pure gold, alloyed with white metals and finished with rhodium plating for a bright, mirror-white shine. It costs less than platinum and is lighter on the finger. As the plating wears, usually over a year or two, a hint of warmth can show; a quick re-plate brings it back. Want to spend less again? See our 9ct white 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.

Usually every year or two, depending on how hard the ring is worn. Re-plating with rhodium takes a short visit to a jeweller and brings back the bright white finish.
