0.50 ct long radiant lab diamond necklace in 18k yellow gold
the long radiant merges round's brilliant faceting with emerald's elongated silhouette—fire and geometry in a single cut. this 0.50 ct lab diamond is bezel set in 18k yellow gold, oriented horizontally to emphasize width across the chest. the continuous frame protects the stone while the east-west placement transforms the classic into something modern. paired with a paperclip chain in 0.45 mm, the architectural links deliver strength in a bold, structured profile. made in japan with exacting precision.
