Oval Lab-Grown Diamond French-Set Halo Engagement Ring

French-set means each accent sits in its own cut-out with metal only at the corners, so light passes through the band instead of bouncing off a wall of it. It is more work than a bead-set shank, and it shows, the shank glitters rather than glints.

The center is a calibrated lab-grown oval diamond, F to G color and VS clarity, offered at 0.75 / 1.10 carats. Calibrated means the stone is cut to a size class rather than sold as a single numbered stone: the carat shown is the class nominal, and the diamond you receive falls inside a tight published range around it. That is the reason this ring costs what it does. If you would rather have an individually selected, individually certificated diamond in this same setting, we will source one and quote it.

The accent diamonds are lab-grown full-cut melee, matched for color against the center so the ring reads as one piece of jewelry rather than a center stone with decoration arranged around it.

Made in 14K White Gold, 14K Yellow Gold, 14K Rose Gold and platinum, then cut and set to your finger size after you order. The price on this page is the complete ring, center included, not a mounting you then have to fill.
