Master the art of mixing with this set of five slender bar earrings. Try these studs in any combination—all look good. 1 1/2mm x 11mm. Gold-plated brass, rose-gold-plated brass, rhodium-plated brass, silver-plated brass. Sterling silver posts are naturally soft due to the high silver content (just bend 'em back into shape if they get out of whack). Care instructions: Clean your jewelry after each wearing with a soft cloth.
