Explore M Grace's round brilliant cut collection — fine jewelry rings, earrings, and necklaces centered on lab-grown round brilliant cut diamonds, set in platinum, 18K yellow gold, and 18K rose gold.

The round brilliant cut is the most popular diamond cut in the world, engineered with 58 facets to maximize light return and brilliance. This collection showcases the cut across a wide range of settings — solitaires, halo designs, frame studs, ribbon-style pendants, and multi-stone arrangements — with diamond carat weights from 0.2ct to 5ct.

Select pieces pair round brilliant diamonds with lab-grown colored gemstones, fancy-color diamonds, or Akoya pearls, offering versatility across styles and occasions. Each piece is made to order using Japanese goldsmithing techniques, with precise stone setting that allows the round brilliant cut to perform at its best.
