A cleverly curving band defines the flat twist princess cut diamond engagement ring, securing the stone without an intricate setting and lending a modern, sophisticated line. Choose from platinum, 18ct yellow or rose gold, with a GIA-certified F-colour Si1 princess cut diamond in sizes from 4mm to 6mm, equating to diamond weights from 0.4ct to 1.2cts.
Handmade in our Ditchling workshop in Sussex, where the flat twist band is worked by hand to curve around and hold the princess-cut stone — a distinctive take on engagement rings that blends modernity and tradition.

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.
