Inspired by pebbles trapped in wood along the Sussex coast, the trap trilogy diamond engagement ring centres a GIA-certified FVS2 round brilliant cut diamond of 0.33ct (4.5mm) or 0.5ct (5.2mm).
Handmade in our Ditchling workshop in Sussex, choose between 9ct or 18ct gold and platinum. The central diamond is accompanied by two 2.2mm round diamond side stones, for a total carat weight of 0.45cts or 0.75cts.
To lay out the detail: the centre diamond is 0.33ct/4.5mm or 0.5ct/5.2mm, GIA-certified FVS2; the side stones are two 2.2mm round diamonds; the total carat weight is 0.45cts or 0.75cts; and the width is 7/8mm at the front, 4mm at the back.
A quietly unusual choice among engagement rings, drawn from the Sussex coast. Book a free appointment, online or in-store, to compare the two diamond sizes.

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.
