What are eternity rings, and are half-eternity bands more practical?

ZKZ Editorial TeamMain answer · Product & gemmology desk

A half-eternity band is generally the more practical choice: the plain section at the back sits comfortably, can be resized and has fewer stones to maintain. A full eternity gives a complete circle of sparkle but is harder to size, repair and wear comfortably.

Full eternity

Our advice Stones run all the way round the band. It looks continuous and has no wrong side, but the stones press against neighbouring fingers and the palm, and the band cannot usually be resized without damage.

Half-eternity

• Stones cover the top half or two-thirds
• Plain metal at the back that is more comfortable
• Often possible to resize within limits
• Fewer stones to check and replace

Practical comparison

• Resizing. Full eternity: Difficult; Half eternity: Often possible.
• Comfort. Full eternity: Variable; Half eternity: Usually good.
• Stone count. Full eternity: High; Half eternity: Lower.
• Cost. Full eternity: Higher; Half eternity: Lower.
• Care. Full eternity: More checks; Half eternity: Fewer checks.

Wear and care

Our advice Any ring with stones all round needs checking for loose stones and worn metal. Stones on the palm side take more knocks.

Choosing

1. If you want a ring you can resize and wear every day, choose a half eternity.
2. If you want the full circle of stones and accept the limits, choose a full eternity and measure carefully.

It depends The choice depends on how important the continuous look is and how comfortable you want the ring to be.

What to ask the seller

• How many stones are there, and how are they secured?
• Can the band be resized, and by how many sizes?
• Is the inside of the band smooth and comfortable?
• What is the policy if a stone is lost in the first year?

Our advice Think about the setting and what the wearer does with her hands. If she works with her hands, the half-eternity usually has fewer places for a stone to catch.

Uncertain We cannot tell how a particular eternity band will feel without trying it.
