Platinum princess cut 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. Platinum is naturally white, so it never needs re-plating, and it is dense and hard-wearing, which keeps claws and small diamonds secure for decades.
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.
Why platinum?
We use 950 platinum, hallmarked in the UK. It is about 95% pure, so it is naturally white all the way through and never needs re-plating. It is heavier than gold and very hard-wearing: rather than wearing away, the metal moves over time and takes on a soft satin look, which a quick polish brings back to a high shine. It is also the best choice if you have sensitive skin.
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.
All precious metals mark with wear. Platinum moves rather than wearing away, so it keeps its weight and holds the diamond securely. Over time it takes on a soft satin finish, and we can polish it back to a bright shine whenever you like.
