The Round Brilliant Cut Diamond Ring (4ct) is fantastic as a wedding or eternity ring to be worn alone, or with an engagement ring. It stacks well alongside wedding or eternity rings, or can be worn as a stand-alone piece.
Lovingly handmade in platinum or 18ct yellow gold, the ring is channel-set with a total of 16 x 4mm (0.25ct) round brilliant cut diamonds, amounting to 4cts in total (varies a little with ring size); we use certified GIA F colour (white) VS2 clarity (eye-clean) natural diamonds. With a 6mm wide court-shaped band, the ring provides a comfortable fit while making a bold and impressive statement. Discover more designs in our unusual rings collection.

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.
