Follow these simple steps to keep your pieces looking their best: Avoid direct contact when applying cosmetics, perfumes, sprays, creams and oils. Store jewelry in a clean, dry place away from natural sunlight, humidity and heat. Each piece should be stored individually in an air-tight pouch (especially sterling silver and gold vermeil to prevent oxidation, tarnishing and scratching). Remove jewelry before swimming, bathing or showering. Remove rings before washing your hands. To remove tarnish, buff gently with a soft polishing cloth.
