Buying guide

What a baguette band looks like

A baguette is a long, rectangular step cut. Instead of the bright sparkle of a round brilliant, it gives clean flashes of light and a sleek, architectural look. Set end to end, baguettes form a smooth line of light; set east-west, turned sideways across the band, they give a wider, more modern look.

Setting styles

  • Channel set: the lab-grown diamonds sit between two metal walls, which keeps the surface smooth and the stones well protected.
  • Bar set: thin metal bars separate the stones, leaving the sides open to light.
  • Shared prongs: small prongs hold neighboring stones, so more of each baguette shows.
  • Half or full eternity: stones across the top only, or all the way around.

Platinum, weight and price

Platinum is dense and naturally white, so it holds the straight edges of baguette lab-grown diamonds securely and never needs plating. Most designs offer options between about 0.25 and 1.5 carats total weight, and a few go up to 5 or 6 carats. Prices start from about $1,000 at the smallest option, and most are between about $1,350 and $1,550.

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, so for those the one free size change means remaking the band.
