Diamonds are remarkably durable, resistant to scratching except by another diamond, and maintain their brilliant fire extremely well. These qualities make a diamond well-suited to regular wear and are perfect for engagement and wedding rings, which are usually worn every day.
But even a diamond isn't indestructible. It can be chipped by a sharp blow or become loose in its setting and fall out. A diamond should be worn with care.
Because diamonds tend to pick up grease and oils, they can become dirty with handling and should be occasionally wiped with a lint-free cloth. Other methods for safe cleaning include warm water, mild soap, and a soft toothbrush or a commercial cleaning solution. It is not recommended to use ultrasonic and steam cleaners.
