Apply lotion, cosmetics, hairspray and perfume before dressing in jewelry.
When undressing, wipe each piece with a clean soft cloth to remove oils and perspiration.

Never wear jewelry when doing physical work such as housekeeping, gardening or exercise.
Never expose jewelry to household cleaning products.
Never expose jewelry to chlorine swimming pools or hot tubs.
Follow the instructions appearing on the label or box.
Clean in a secure location, not the rim of a sink where a piece may slip down the drain.

Seriously soiled jewelry should be cleaned professionally.
Clean diamond jewelry with a soft brush dipped in warm water and mild detergent; rinse under running water.
Never expose pearl jewelry to chemicals or solvents and store each piece in a soft bag.
Don't expose colored gemstones to chemicals, solvents or ultrasonics without knowing their specific cleaning requirements.
