Buying guide

Half eternity or full eternity

A half eternity lab-grown diamond band has stones only where they show, across the top, while a full eternity band runs them all the way around. The plain back makes a half eternity band more comfortable between the fingers, lowers the cost, and lets the ring be resized, which a full circle of stones does not allow. From the front, the two look almost the same.

Settings and stone shapes

  • Shared prongs: each lab-grown diamond shares small prongs with its neighbor, so little metal shows and the row looks continuous.
  • Channel and bar set: stones held between metal walls or separated by thin bars, a smooth choice for active hands.
  • Bezel and pavé: a metal rim around each stone, or many small stones set close together.
  • Shapes: round for the most sparkle, emerald cut, asscher and baguette for clean steps of light, marquise and cushion for a softer outline.

Curved designs dip to sit flush beside an engagement ring, and men's half eternity bands set stones flush or in a wider band.

Carat weight, metal and price

Carat options are the total weight of all the lab-grown diamonds in the band. Most designs offer from 0.25 to 0.75 carat total weight, many go to 1 or 1.5 carats, and a few reach 5 carats or more. Gold comes in 10K, 14K or 18K on most designs. Prices start under $200, and most bands cost between about $600 and $850.

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.

Lab-Grown Diamond Half Eternity Wedding Bands FAQs

Can a half eternity ring be used as a wedding ring?

Yes. A half eternity ring is one of the most common wedding ring choices. It gives a full line of sparkle from the front while the plain back stays comfortable and can be resized. Many people wear one alone or stacked against an engagement ring, and the curved half eternity bands in this collection are shaped to sit flush beside a raised center stone.
