These 14 karat yellow gold stud earrings feature .50 carats of emerald cut natural diamonds with I color and VS2 clarity. The diamonds are collet set, which gives them a clean, simple look that lets the stones do all the talking. Post backs keep them secure and comfortable. The emerald cut gives these studs a different look from traditional round diamonds, with their rectangular shape and step-cut facets creating their own distinctive sparkle.
