Overview Specs Documentation These gold-plated sterling silver studs pair a smooth oval cabochon with sparkling accent stones for a look that's polished and elevated. Choose your center: golden-needled rutilated quartz, deep green onyx, or rich purple amethyst — each one bringing its own color and character. The rounded, dome-cut center stone brings a soft glow while the surrounding accents add just the right amount of shine. Classic enough for everyday and refined enough to dress up, they're an easy go-to for any look.
