Full or half eternity?

Half eternity is more comfortable and easier to resize. Full eternity means diamonds no matter how your hand turns — worth the tradeoff for many people.

Can you resize a full eternity?

Barely — usually only by half a size. Get the size right at purchase.

Best stone shape for eternity?

Round is timeless. Emerald or baguette is editorial and modern. Oval is a full statement.

Where does eternity go in a stack?

Usually below the engagement ring (closer to the knuckle) so it doesn't sparkle-compete. Some people wear it above and love it.

What it actually looks like

An eternity band is a ring with diamonds all the way around — no beginning, no end. It's the ring most people add for a five-year, ten-year, or first-baby anniversary, and increasingly the wedding band choice for people who want maximum sparkle.

Full eternity means diamonds around the entire band. Half eternity means diamonds only on the top-facing half — more comfortable to wear, easier to resize.

Stone shape matters. Round eternity is the classic. Emerald or baguette eternity feels more editorial. Oval eternity is a statement.

How thick to go

A 1.5mm round eternity band is delicate and stacks beautifully with almost anything. 2.5mm is substantial and reads more like a standalone statement ring.
