Details
Diamonds that seem to float in little cradles of light. This band holds 2.5 mm round brilliants in U-shaped prongs, open scoops of metal that lift each stone and let light slip in from below all the way around.
Those U-prongs show off more of each diamond's sides than a standard setting, so the band looks airy and bright for its size. Choose lab-grown for the most sparkle per dollar or natural diamonds, in 14K gold or platinum. Total carat runs near 1 1/2, with a little more as the size grows.
Open and light-filled, it makes a striking anniversary or milestone gift. Stack it against an engagement ring or wear it alone as a luminous band.
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.
| Finger size | Lab-grown CTW | Natural CTW |
|---|---|---|
| 4.5 | 1 3/8 | 1 3/8 |
| 5 | 1 3/8 | 1 3/8 |
| 5.5 | 1 3/8 | 1 3/8 |
| 6 | 1 3/8 | 1 3/8 |
| 6.5 | 1 1/2 | 1 1/2 |
| 7 | 1 1/2 | 1 1/2 |
| 7.5 | 1 1/2 | 1 1/2 |
| 8 | 1 1/2 | 1 1/2 |

Answers, before you ask
Your Questions
Is it resizable?
No. With diamonds set around the entire band there is no plain metal to size, so it is made to your finger size. Please confirm your fit first.
Lab-grown or natural?
Both are real diamonds with matching sparkle. Lab-grown gives more shine per dollar; natural is mined. Pick at checkout.
What carat weight will I receive?
Near 1 1/2 carat total, nominal, rising slightly with size as the band holds more stones.
Do the open U-prongs hold the stones securely?
Yes. They cradle each diamond firmly while letting in extra light. As with any prong setting, a periodic check keeps them tight.
