The trap diamond engagement ring (4mm) is a unique and versatile design, a practical and stylish choice that seamlessly complements existing engagement or wedding rings with a similar shank style. It is set with twelve small round diamonds, in a size to suit your centre stone choice.
Handmade in our Ditchling workshop in Sussex, it comes in 9ct or 18ct yellow or rose gold, or platinum. Natural diamonds are GIA-certified F colour VS2 clarity round brilliant cut, and lab-grown are IGI-certified D colour VS1 clarity — all graded excellent for cut, polish and symmetry. The ring is 4mm wide, expanding to 6mm at the front.
To recap the detail: the diamonds are twelve small round stones, natural GIA-certified F/VS2 or lab-grown IGI-certified D/VS1; the metals are 9ct or 18ct yellow or rose gold, or platinum; the width is 4mm, expanding to 6mm at the front.
The band can be curved to fit and complement existing rings — a modern, wearable take on engagement rings.

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.
