From GIA Blog: Diamonds are remarkably durable, resist scratching (except by other diamonds) and maintain their brilliance over time. But diamonds aren’t indestructible. They can be chipped by a sharp blow, become loose or lost in a weakened setting, or be damaged by contact with other diamonds.
Wear diamond jewelry with care. Store it in padded boxes or soft bags separate from other jewelry.
Clean your jewelry by wiping it with a lint-free cloth or with warm water, mild soap and a soft toothbrush, or by dipping it briefly in a commercial cleaning solution.
Bring your diamond jewelry to Dynasty Jewelry and Loan periodically cleaned and its setting examined by a one of our professional jewelers to maintain its beauty and integrity over time.
