Mine-cut diamonds give this offset old cut diamond platinum engagement ring its distinctive charm, combining one 4-4.5mm stone with three 3-3.2mm stones, each with its own rocky shape and character, on a 2.5mm recycled platinum band made for both comfort and stability.
Every ring is shaped and finished by hand in our Ditchling workshop in Sussex, where we have made fine jewellery since 1988.
There is the option to add a fitted 2.5mm wedding band to match, creating a harmonious set among our engagement rings — book a free online or in-store appointment to see the diamonds in person.

Ring fit guide
Our bands have a comfort-fitted inner, so they feel slightly looser than a flat band — order your true size.
Tap a row to select that size.
- Measure when your hands are at room temperature — not too warm, not too cold.
- Cold hands measure up to half a size smaller — avoid measuring in winter or after exercise.
- A wider band needs a slightly larger size: at 6mm and above, go up a half size.
Still unsure? We post a free ring sizer the same day. Every ring comes with one free resize, whenever you need it — there is no time limit. The sizer is free with the code FREERINGSIZER — the button below applies it for you.
