Platinum Lab-Grown Diamond Channel Set Wedding Bands

Each channel set platinum wedding band holds its lab-grown diamonds in a groove between two walls of metal, with no prongs. Choose round, princess cut or baguette lab-grown diamonds, set across the top as a half eternity band or all the way around as a full eternity band. Some are wider men's wedding bands, and a few add milgrain, curves or engraving.

Buying guide

How a channel setting holds the stones

In a channel set platinum band, the lab-grown diamonds sit side by side in a track, held at their edges by the metal walls. Nothing sticks up to catch on clothing, which makes it a good choice for hands that work. The smooth rails also show the platinum as part of the look.

Round, princess or baguette

  • Round lab-grown diamonds give a soft, sparkling line.
  • Princess cut lab-grown diamonds sit square to square for an unbroken row.
  • Baguette lab-grown diamonds add long, straight facets for a sleek, modern band.

Some designs add bar dividers between stones or a double row for a bolder band.

Total weight and price

Most designs offer about 0.25 to 1 carat total weight, and a few go higher. Most bands here are half eternity, which leaves plain metal on the underside. Bands start under $900 at their smallest option, and most are between about $1,600 and $1,950.

Made to order

Each band is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery. Full eternity bands can't be resized: the one free size change within 60 days means remaking the band.
