An eternity lab-grown sapphire band carries lab-grown sapphires all the way around the finger, so the color shows from every angle. These wedding bands set blue or pink lab-grown sapphires in shared prongs, in emerald cut, marquise and oval shapes, and come in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver. Some styles are made as men's bands.
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
In a full eternity band the stones meet end to end around the whole ring. Shared prongs hold each pair of neighboring lab-grown sapphires with one small claw, which keeps the metal light and lets more of each stone show. Emerald cut stones set north-south give a clean, step-cut line of color; marquise stones form a pointed, leaf-like chain; oval stones give a soft, even row that suits a wider, heavier band.
Because stones run all the way around, a full eternity band can't be cut and resized the way a plain band can. Measure your finger at the end of the day, when it is largest, and size for the knuckle so the band slides on without forcing. A full eternity band also sits best on its own or beside an engagement ring with a straight band.
Lab-grown sapphire rates 9 on the Mohs scale, just below diamond, which makes it a strong choice for a ring worn every day. A lab-grown sapphire has the same chemistry and hardness as a natural sapphire and costs far less than a natural stone of the same size and color. Blue looks deep in white gold or platinum, and pink looks soft in rose or yellow gold. Prices start under $200, and most bands are between about $350 and $825 at their smallest option.
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, with stones all the way around, can't be resized: the free size change means remaking the band.
