THE DETAILS

Lab-Grown Gemstone Eternity Rings, Explained

Straight answers from the people who make the rings. Every ring is backed by a Lifetime Limited Labor Warranty and a 30-day return window, ships free in the US, and can be financed through Affirm at checkout. Anything not answered here, contact us and we’ll answer it.

Same mineral, same hardness. Optically they read the same. What differs is origin and price: growing the stone is what controls the color, and it costs a fraction of the mined equivalent. Every color stone on this page is lab-grown, and the diamonds set alongside them are natural.

Blue sapphire, ruby and emerald, all lab-grown, each one set with natural diamonds. Today that is 34 emerald designs, 32 ruby and 23 sapphire.

Prices in this collection range as low as $1,045.99, and the top of the collection is $3,933.99. What moves the number is the metal, the total carat weight and the stone. You’re buying from the shop that makes the ring, so you pay for the stones and the work, not a showroom’s rent.

Hardness decides it. Sapphire and ruby are 9 on the Mohs scale, just under diamond at 10, so they take daily wear well. Emerald is softer, roughly 7.5 to 8, so it wants more care: take it off before the gym or the dishes. The natural diamonds set with all three are the hardest thing on the ring.

Yes. Every design here is made to order. Choose 14K or 18K white, yellow or rose gold, or platinum, and tell us which color stone you want set. Making the ring takes 5 to 7 business days, and US shipping is 1 to 3 business days depending on the option you pick at checkout. If you want a layout we don’t show, our jewelers will design one from your idea or your sketch.

About Our Lab-Grown Gemstone Eternity Rings

Color is the whole point of a ring like this, so we make it where we can control the color: cast, set, and polished in our own US factory, as we’ve done since 2001. The sapphires, rubies and emeralds are lab-grown, and that is what keeps the color affordable.

Every one of the 89 rings is an eternity design set with natural diamonds and made to order in 14K or 18K white, yellow, or rose gold, or platinum, with prices in this collection ranging as low as $1,045.99.

Nothing is made until you order it, so the metal and the stone are your call. Pick a ring above, or contact us and we’ll help you choose.
