Oval Lab-Grown Diamond Three-Stone Halo Engagement Ring

A halo of small diamonds ringed around the oval, which makes a 0.75 carat centre read closer to a carat and a quarter on the hand. That is the entire economic argument for a halo, and it is a good one. One rung only: at larger centres the halo stops helping and starts crowding.

The centre is a calibrated lab-grown oval diamond, F–G colour and VS clarity, offered at 0.75 carat. 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 colour against the centre so the ring reads as one piece of jewellery rather than a centre 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. From $2,239 for the complete ring, centre included — the price on this page is the ring, not a mounting you then have to fill.

The side stones are pear-shaped lab-grown diamonds, 4.00 × 3.00 mm, one either side of the oval, with a round halo ringed around the centre. We spell that out because “halo” on its own would have you picturing a different ring.

If this is a gift, the practical notes: we build it to your ring size, so nothing has to be guessed at the moment it matters, and if the size is wrong we resize it free in the first year. Every ring is made to order, which also means the person wearing it can change the metal or the centre size afterwards with a conversation rather than a return.

One care note: a pear has two points, and points are the part of any stone a setting has to protect. Both apexes here sit under prongs rather than proud of them. We check them at every service, and re-tip them under the lifetime warranty.
