Buying guide
A half eternity band carries aquamarines across the top and leaves plain gold underneath. It is comfortable to wear every day, stacks easily beside an engagement ring, and can be resized later. A full eternity ring has aquamarines all the way around, so the color shows from every angle, but it has to be ordered in the right size.
Aquamarine is the blue variety of beryl and the birthstone for March. It rates 7.5 to 8 on the Mohs hardness scale, hard enough for a ring worn often, though a sharp knock can chip an edge. Yellow gold warms the pale sea blue and gives the band a soft, vintage feel. An aquamarine eternity ring in yellow gold also pairs well with other gold rings.
Prices start under $400, and most bands are between about $550 and $750.
Each band is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery. Full eternity bands can't be resized, so for those the one free size change means remaking the band.
