Platinum radiant cut engagement rings, handmade to order by our family workshop in the Cotswolds and set with a diamond you choose yourself. The radiant cut combines the clean outline of an emerald cut with the fiery sparkle of a brilliant. 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 radiant cut diamond
The radiant has the cut corners of an emerald cut but brilliant facets inside, so it sparkles more than any other square or rectangular shape. The cut corners make it hard-wearing, and it comes square or elongated.
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 radiant diamond
Our diamond search splits radiants into square and elongated. A ratio of about 1.00 to 1.05 gives a square; 1.20 to 1.35 is a popular rectangle. The brilliant facets hide small inclusions well, so SI1 clarity often looks clean.
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
No. Both are brilliant cuts, but a radiant has cut corners, which make it tougher and softer-looking, and it can be square or rectangular. A princess is always square with sharp corners.
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.
