Details
Two millimeters is the sweet spot, and here it circles the finger without a break. Round brilliants nearly 2 mm across sit in shared prongs all 360 degrees, a full carat's worth of light with no clasp, no gap, no wrong way to wear it.
Larger stones mean bigger flashes of fire, and the shared-prong line keeps them locked shoulder to shoulder for an unbroken sweep. Choose lab-grown for the most carat for your budget or natural diamonds if you prefer, in 14K gold or platinum. Total weight sits around 1 carat and ticks up slightly on larger sizes.
It makes a generous anniversary gift and an even better everyday ring. Wear it as a wedding band, stack it with your engagement ring, or let it stand alone.
Total carat weight by finger size. A full eternity band holds more diamonds at larger sizes, so the total weight grows with the size you order.

Answers, before you ask
Your Questions
How wide is it, and what is the fit?
It measures about 2.1 mm wide. Measurements are approximate and vary slightly with the ring size.
Which diamond type options are there?
Choose lab-grown or natural on this page. Each option is priced on its own, and the price updates when you change it.
Which metals can I choose, and is it solid?
Choose 14K white, yellow or rose gold; or platinum. All the gold is solid 14K, never gold-plated. White gold is finished with rhodium, which a jeweler can refresh over time.
What are the diamonds?
It is set with 25 to 31 natural or lab-grown round diamonds, depending on the size: 2 mm each, about 1/10 ct, and about 3/4 to 1 ct in total.
Does the carat weight change with size?
Yes. The diamonds run all the way around, so a larger size holds more stones and a smaller size fewer. The weight on this page is for the size shown in the option you choose.
Which sizes are offered, and can it be resized?
US sizes 4 to 9, in half sizes. Each size is made individually, so it can't be resized later; please confirm your size first.
Can I return or exchange it?
Rings are final sale, as each is made or sized to your size; please confirm it first, and our concierge can help. If it arrives damaged, defective or not as ordered, tell us within 7 days of delivery and we'll repair, replace or refund it.
How do I care for the diamonds?
Diamond is the hardest gem, though a hard knock can still chip an edge. Warm water, mild soap and a soft brush restore the sparkle.
