Lab Grown Diamond Eternity Bands

Full eternity bands cannot be resized because the diamonds are set all the way around, and there is no plain metal section to add or remove material to adjust the ring size. Even if a full diamond needs to be removed to get to the proper ring size, the whole band has to be reconstructed.

This is the most important thing to confirm before ordering, and you can check our Ring Size Guide to help find the perfect fit.

A few tips: Measure your finger at the end of the day when fingers are slightly larger, and size up a quarter or half a size if you fall between sizes. Keep in mind that stacking additional rings will make the fit feel tighter over time, so if you plan to build a stack, sizing up slightly is worth considering.

If you want the look of an eternity band with future sizing flexibility, half and three-quarter eternity bands are available as custom orders. Contact us through the custom jewelry form and we can create one to your specifications.

A wedding band is any ring worn to mark a marriage. It can be plain metal, partially set with stones, or fully set all the way around. An eternity band is a specific style: diamonds set continuously around the entire circumference of the ring. Many people choose an eternity band as their wedding band, which is a perfectly appropriate choice. Others use eternity bands as anniversary gifts, stackable additions, or standalone pieces worn for no occasion at all. There is no rule about when or why to wear one. The only practical consideration is that because diamonds run all the way around, full eternity bands cannot be resized.

Price is determined by total carat weight, individual stone size, diamond shape, and setting style. Delicate stackable bands start under $1,000 at 1 CTW. At 2-3 CTW, where each stone is approximately 10-15 pointers, eternity bands run $1,500-$2,500. At 5-6 CTW, each stone reaches 25-33 pointers and pricing runs $2,250-$3,000. At 8 CTW, stones approach 50 pointers and bands start around $3,500. At 12–14 CTW, each diamond is approximately 1 carat, with prices starting around $4,500.

For mined diamonds, individual stone size is what drives the price up exponentially, and why the gap between lab grown and mined widens so dramatically at higher carat weights.

At 3 CTW, comparable F/VS natural diamond eternity bands run $5,000–$9,000+ from reputable retailers, roughly 3-5x the lab grown price. At 5 CTW, F/VS natural diamond bands run $13,000–$22,000, roughly 5-9x more. At 8 CTW with 50-pointer stones, natural diamond pricing reaches $20,000–$45,000+. At 12 CTW where each stone is approximately 1 carat, the mined diamond equivalent runs well into six figures, as much as 20x more than the lab grown equivalent. The diamond is the same.

Shared prong settings hold each diamond with small metal claws shared between adjacent stones, maximizing the amount of light that enters each stone. It's the most open and sparkly option, and the most popular. Bezel settings wrap each stone in a continuous metal edge for a sleeker, more modern look. A half bezel has a continuous metal edge around the top and bottom of the diamonds, but not in between. They are also completely snag-free and slightly more protective of the stone edges. East-west orientations turn fancy shapes like emerald and radiant cuts sideways across the finger, creating a wider, more architectural profile. If you're stacking multiple bands, a mix of settings adds visual texture. If you want maximum sparkle from a single band, shared prong is the standard.

An eternity band works alone, stacked with other bands, or alongside an engagement ring. Bands in the 1-3 CTW range, where each stone is 10-20 pointers and the profile is delicate, are well suited for stacking multiple rings on the same finger without feeling heavy or bulky. At this size they will also typically sit flush with most engagement rings. At 5-8 CTW, a single band already makes a real statement on its own, though two or three can still be stacked for a bolder look. At 10-14 CTW, where each stone is 0.75-1 carat, the band commands the finger entirely. Stack two of these and you'll know it — and so will everyone else.

When building a stack, keep in mind that each additional ring makes the fit slightly tighter. If you're planning to add rings over time, especially with larger stones, sizing up a quarter to half size gives you room. Varying the setting style or stone shape across bands adds more visual interest than matching everything perfectly.

Yes. Every diamond in these bands is a real diamond: same carbon crystal structure, same hardness, same brilliance as any mined diamond. Lab grown diamonds are physically and chemically identical to mined diamonds and are graded by the same gemological laboratories using the same 4Cs standards. The only difference is where they formed. The eternity bands in this collection are not certified individually, but every stone is held to F+ color and VS+ clarity standards.
