It suits someone who wants a diamond band with real presence rather than a thin sparkle line, and who plans to wear it daily next to an engagement ring or on its own. Within our rings collection, this is the one built around larger stones in a shorter row.

Why Are There Only 15 Stones on This Band?

Most pave bands at this width use 30 or more stones under 2 mm each. This one uses 15 at roughly 2.85 mm, so each stone carries about 0.08 ct on its own. Fewer and larger stones means fewer prongs interrupting the row, a wider spread of light per stone, and a line that reads as individual diamonds rather than continuous glitter.

The band finishes at 2.98 g in 14K white gold at size 52, with a rounded outer profile and a smooth inner wall. The diamond row covers 75% of the circle, which is the whole visible top of the hand, and leaves a solid section of gold at the palm side. That solid section takes the daily knocks, sits comfortably against a neighboring ring, and leaves a jeweler something to work with if the ring ever needs sizing. A full eternity band has no plain metal to cut into, so sizing it means removing stones and rebuilding the row.

What Metal and Diamonds Are Used?

The band is solid 14K white gold throughout, stamped Au 585 with the Redora mark and the ring size on the inner wall. The stones are lab grown diamonds, round brilliant cut, matched for color and size across the row before any of them are set. Diamonds of this size are set as accent stones rather than graded individually, so no per stone report is issued. A test certificate covering the 14K gold and the diamonds is available on request.

• ◆ Each seat is cut into the solid band at the bench, so the stone sits at a depth matched to its own diameter rather than a cast average
• ◆ Prongs are raised from the band metal itself and shared between neighboring stones, then tightened one at a time with a rotary graver
• ◆ The metal beside and between the row is brought back with a rubber wheel before polishing, which is what keeps a clean bright edge on both rails
• ◆ Every stone is checked for tightness and table alignment after polishing, and the inner wall is finished last so nothing catches on the finger
