Radiant Solitaire Engagement Rings: What Goes Underneath

In this guide

    By Clint Casmiro, Co-Founder, Smiro Studio · Updated October 22, 2026

    Short answer: A radiant solitaire is one radiant cut diamond on four prongs with no side stones, and the detail goes underneath. Three we built for clients: a 3.01 carat radiant in 14K yellow gold over a tulip basket and a curved gallery rail, a 2.5 carat radiant in yellow gold with a curved hidden halo and tulip, and a 2.5 carat radiant in 14K white gold with pavé halfway down the band.

    A solitaire keeps the top view to one stone. What changes between these three is what sits under it and what runs down the band.

    What does a radiant solitaire with a tulip look like?

    Plain on top, with a tulip basket and a curved gallery rail giving the side view some shape.

    Calum's ring: 3.01 carat radiant, 14K yellow gold.

    Setting
    Solitaire, four prongs, tulip basket, curved gallery rail
    Band
    14K yellow gold, 2 mm half round

    The 2 mm band keeps it delicate, and the side profile has enough detail to catch the light. See Calum's ring.

    Can a radiant solitaire have a hidden halo?

    Yes. A curved hidden halo sits under the stone and the top stays a solitaire.

    Daniel's ring: 2.5 carat radiant, 14K yellow gold.

    Setting
    Solitaire, tulip setting, curved hidden halo
    Band
    14K yellow gold, 2 mm half round

    The halo adds sparkle from the side without taking attention from the stone. See Daniel's ring.

    Can a radiant solitaire have pavé?

    Yes. Here pavé runs halfway down a white gold band, and the top still reads as one stone.

    Choose by what you want beneath the stone.
