Buying Guide
The sizing constraint is the first thing to understand, because it is the one ring in our range where our free resize does not apply. Stones run the whole way round, so there is no plain section of metal for a jeweller to cut and rejoin — an eternity ring that is the wrong size has to be remade rather than adjusted. Have the finger measured properly before ordering.
Half eternity is the more practical choice for most buyers: stones cover the visible top of the finger while the plain underside takes the wear against the palm and remains resizable. A full eternity gives an unbroken line from every angle, which is the reason to accept the constraint. Either way, evenness across the line matters more than any single stone, which is what our D–F colour floor protects. Made to order with free worldwide shipping and 30-day returns.
Frequently Asked Questions
Can eternity bands be resized?
No. Stones run the full circumference of an eternity band, so there is no plain section of metal to cut and rejoin. An eternity ring has to be ordered in the correct size and remade if the size is wrong. We recommend having the finger measured properly before ordering — this is the one ring where a resize is not an option.
Why can’t eternity rings be resized?
Because there is no plain metal to work with. Diamonds run the full circumference, so a jeweller cannot cut the band and rejoin it without disturbing the settings. An eternity ring has to be made in the correct size and remade if the size is wrong — the one ring in the range where our free resize does not apply.
Full eternity or half eternity?
Half eternity is the more practical choice for most buyers. Stones cover the visible top of the finger while the plain underside can be resized and takes the wear against the palm. A full eternity gives an unbroken line from every angle, which is the reason to choose it, and commits you to the size you order.
Which ring styles are most popular for stacking and layering?
Eternity and anniversary bands stack best, because an unbroken line of stones sits flat against whatever it is next to. We build 35 eternity and 135 anniversary designs, which is where most stacks start. The variable that actually decides it is profile rather than style: a low flat band will sit against anything, while a raised solitaire needs a contoured band beside it to close the gap.
Can I order a ring if I don’t know the finger size?
Yes. We include one free resize within 30 days of shipping on U.S. orders, which covers most cases. The exception is eternity rings, which cannot be resized and must be ordered to size. If you are unsure, book a free 30-minute video or phone consultation and we will talk you through measuring.
