An aquamarine eternity band sets a row of natural, treated aquamarines along the band. Most designs here are half eternity bands, with stones across the top, and a few are full eternity rings with stones all the way around. Choose round stones or marquise, pear, princess and emerald cuts, in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver.
From a slim 1.5mm to a bold 6mm — choose the proportion that suits your hand.
A gently rounded interior that slips on easily and wears beautifully all day.
Match or contrast your engagement ring in white, yellow, rose gold or platinum.
Curved and contoured bands designed to sit flush against your ring.
Buying guide
A half eternity band carries aquamarines across the top and leaves plain metal underneath. That makes it comfortable to wear every day, easy to stack beside an engagement ring, and possible to resize later. A full eternity ring has aquamarines all the way around, so the color shows from every angle. Because the stones circle the whole band, a full eternity ring 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 still chip an edge. The color runs from pale, icy blue to a deeper sea blue. Most aquamarine on the market is treated to give a purer blue, and these stones are too. Clean the band with warm, soapy water and a soft brush.
Prices start under $200, and most bands are between about $500 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.
