Two Hearts, One Promise

Round Lab-Grown Diamond Curved Wedding Bands

These round lab-grown diamond curved wedding bands dip in the middle so they sit close to a round engagement ring. Pave lab-grown diamonds run across the top half of the band, and each is made in yellow or rose gold. A curved band shaped for a round center fills the gap a straight band can leave.

Buying guide

Why choose a curved band

Many engagement rings have a head or halo that sits low on the finger. A straight band pressed against it can leave a gap or rub against the setting. A curved band follows the outline of the center, so the two rings sit flush. A curved wedding band with a round engagement ring works especially well because the gentle arc matches the round shape.

How these bands are set

The bands are half eternity: round lab-grown diamonds run across the top of the band, and the lower half is plain metal, which keeps the band comfortable and easy to resize. Settings include a contour pave band with shared prongs, where neighboring stones share the metal that holds them, and a curved pave band with U-prongs, which show more of each stone from the side.

Weight, metal and price

Total weight options run from 0.25 to 0.5 carats total weight, depending on the band. Choose yellow or rose gold; some bands offer 10K, 14K or 18K. Prices start at about $780, and most fall between about $780 and $870.
