The Platinum Diamond Three Strand Trap Eternity Ring is inspired by pebbles trapped in wood along the Sussex coastline. The cool tones of the chalk cliffs are subtly combined for an organic look.

Complimentary Diamonds: Three complimentary diamonds to your feature diamond are used: a 3.2mm and two 2.8mm to match the half carat diamond and a 3mm with two 2.5mm diamonds for the 0.25ct version.

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.
