A lab-grown sapphire eternity band sets a continuous row of lab-grown sapphires around the finger. Every design here comes with blue or pink lab-grown sapphires and in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver. Most are half eternity bands, with stones across the top, and a few are full eternity, with stones all the way around.
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 sets stones across the part of the ring that shows, leaving the underside plain. It is more comfortable next to other rings and can be resized. A full eternity band carries stones all the way around, so it shows color from every angle but has to be made in your exact size. If you aren't sure of your size, a half eternity ring with lab-grown sapphires is the safer choice.
Most designs use round lab-grown sapphires, in prong, shared prong, micro pave or channel settings. Some use marquise, pear, princess or emerald cut stones, or alternate two shapes for a vine-like pattern. Pave and double row designs give a fine, sparkling line, while channel settings hold the stones between smooth metal walls. A few designs twist into an infinity shape or add a knife edge or milgrain detail.
Lab-grown sapphire rates 9 on the Mohs scale, so a lab-grown sapphire eternity band handles daily wear well. 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 and classic in white gold or platinum; pink looks softest in rose gold. Prices start under $200, and most bands are between about $525 and $725 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.
