Lab-Grown Diamond Baguette Eternity Bands

These baguette eternity bands use long, rectangular lab-grown diamonds for a sleek line of light. Choose a half eternity band, with stones across the top, or a full eternity band that goes all the way around. Every design comes in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver.

Buying guide

Settings for a baguette eternity band

  • Shared prongs: small prongs hold each corner, so more of every lab-grown diamond shows.
  • Channel set: the baguettes sit between two smooth metal walls, a snag-free choice for daily wear.
  • Bar set: thin metal bars separate the stones, and some mix baguettes with round lab-grown diamonds.
  • Staggered: baguettes sit at angles for a zigzag look, in full eternity and prong-set versions.

Half or full eternity

A half eternity band is easier to wear next to an engagement ring and can be resized within limits. A full eternity band shows lab-grown diamonds from every angle, but the stones leave no plain metal for a jeweler to cut and adjust. Most designs here are half eternity. An eternity band with baguettes looks at home on its own or stacked with an emerald cut or oval engagement ring.

Carat weight, metal and price

Depending on the design, options run from 0.25 to 1.5 carats total weight, and a few offer larger bands of 3 to 7 carats total weight. Many gold designs come in 10K, 14K or 18K. Prices start around $200 at the smallest option, and most fall between about $600 and $900.

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, with stones all the way around, can't be resized: the one free size change means remaking the band, so it's worth confirming the size before you order.
