A radiant cut has the clean rectangular or square outline of an emerald cut with trimmed corners, but its facets are cut in a brilliant pattern like a round stone. The result is lively sparkle in a shape that looks modern and structured. The trimmed corners protect the stone from chipping. At 5 carats, a radiant center covers a lot of the finger and reads as a bold, bright stone from across a room.
Plain solitaires let the center stand alone, and pave solitaires add small lab-grown diamonds along the band. The hidden halo sets a row of small stones under the center. The cathedral raises the stone on arches over a graduated pave band. A halo design with a three-row pave band and filigree details has a vintage look. The three stone ring and the side accent designs, with marquise and round or pear and round stones, frame the center on both sides. Those accents are extra stones beyond the center.
Every design comes in platinum and in 10K, 14K or 18K white, yellow or rose gold. Platinum costs more and stays naturally white. White gold matches the bright look of a radiant cut, while yellow and rose gold add a warm frame.
