Ronora prices are regular prices, shown as "from" the lowest price in the metal named. Prices checked on October 28, 2026.

The millimeter sizes use the method from our guide to famous engagement rings at actual size.

A real stone cut longer, shallower or deeper will measure differently, and our model has no old mine cut, so treat every size as an estimate. To see any weight on your own hand, open Find Me Diamond.
