The princess cut Art Deco trilogy engagement ring sets a square-cut lab-grown centre diamond between two complementary side stones, its crisp lines and precise symmetry inspired by the strong geometry of the Art Deco era. Choose a 0.5ct or 1.5ct centre diamond, with 0.33ct side stones each in the 0.5ct version or 0.75ct each in the 1.5ct version, for an overall total diamond weight of approximately 1.16ct or 3ct respectively.
Each ring is handmade in our Ditchling workshop in Sussex, where the square centre and its two side stones are set into the clean geometric lines that distinguish this design among our engagement rings.
Bold yet elegant, structured yet full of sentiment. Book a free online or in-store appointment to discuss diamond sizes and metals.

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.
