A lab-grown sapphire eternity band in yellow gold sets a row of lab-grown sapphires across the band. Each design can be ordered with lab-grown blue sapphire or lab-grown pink sapphire. Most are half eternity bands, with stones across the top; a few are full eternity, all the way around. Stones come in round, marquise, pear, princess and emerald cuts in prong, channel and pave settings.
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 has stones across the top half only, so the underside is plain gold. It is more comfortable for many people, costs less, and can be resized. A full eternity band sets stones all the way around for color from every angle, but it can't be resized in the usual way. Most of these lab-grown sapphire eternity rings in yellow gold are half eternity.
Lab-grown sapphire is the same mineral as natural sapphire, corundum, with the same hardness of 9 on the Mohs scale, so it handles daily wear well in a band. Blue looks rich and deep against yellow gold; pink gives a softer, warmer pairing. Shapes add variety: marquise and pear stones make vine-like patterns, emerald cuts sit north-south, and round stones give a classic row.
Most designs offer about 0.5 to 1 carat total weight, a few start at 0.15 carats, and some go up to 7 carats. Gold comes in 10K, 14K or 18K on nearly every design. Bands start from about $350, and most are between about $600 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: the one free size change within 60 days means remaking the band.
