Learn · Eternity and anniversary bands
Eternity bands
Stones around the band: a half, three-quarter or full circle.
What it is
Half eternity
Stones across the top half of the band; a plain back.
Three-quarter eternity
Stones most of the way around, with a short plain section underneath.
Full eternity
Stones all the way around.
Shared prong
Each prong holds the edge of two neighboring stones.
Channel set
Stones sit in a groove between two metal rails.
Bezel set
Each stone in its own metal rim.
Why people love it
Half eternity
- Can be resized.
- Comfortable; the plain back sits against the finger.
Three-quarter eternity
- Looks like a full eternity from almost every angle.
- Still has a little room to resize.
Full eternity
- Sparkle from every angle; it never needs turning.
Shared prong
- The least metal, so the most light and sparkle.
Channel set
- Smooth to wear; nothing to catch.
- Protects the stones’ edges.
Bezel set
- The most protective and the smoothest.
- A modern, bubbly look.
Trade-offs
Half eternity
- The plain back shows when the ring turns.
Three-quarter eternity
- Less resizing room than a half.
Full eternity
- Usually can’t be resized much, so the size has to be right from the start.
- Stones underneath take the most wear.
Shared prong
- Prongs can catch; a check now and then keeps every stone.
Channel set
- The rails cover a little of each stone.
Bezel set
- The most metal, so a little less sparkle.
