Eternity Rings by Width

Choose your eternity ring by width, from fine bands of 1mm to bold rings of 5mm and more. Narrower bands stack neatly beside an engagement ring; wider bands hold larger diamonds and make a ring that stands on its own. Pick a metal above to see each width in platinum or 18ct gold.

Eternity Ring Widths

  • Skinny (under 2mm): fine, delicate bands for stacking, or for a small engagement ring.
  • Narrow (2mm to 3mm): the most popular width. Sits neatly beside most engagement rings.
  • Medium (3mm to 4mm): larger diamonds and more presence, still comfortable every day.
  • Wider (over 4mm): bold rings that stand on their own, often worn on the right hand.

How to Choose the Width

Match the width of your engagement ring's band, or go slightly narrower so the engagement ring stays the focus. Wider bands fit more snugly, so for 4mm and over many people go up a quarter or half size. Not sure of your size? Order a free ring sizer.

Thin Eternity Rings

A thin eternity ring of 1mm to 2mm is the subtle choice: a fine line of sparkle that stacks beside a wedding ring or a second eternity ring. Choose a full eternity band for diamonds all the way round, or half eternity for the most comfort.

A band under 2mm wide with small diamonds set along it. It is delicate, comfortable and made for stacking with other rings.

It looks most balanced when the widths are close, but it is a matter of taste. A slightly narrower eternity ring keeps the engagement ring as the focus.

Wider bands fit more snugly, so for 4mm and over many people go up a quarter or half size. A free ring sizer helps you check.
