Clean your diamond jewelry in one part ammonia and six parts water. Using a soft brush, gently scrub prong-set diamonds to loosen dirt. Be careful not to scratch the metal of your jewelry mounting.
It is recommended that you have your diamond jewelry professionally cleaned at least once a year. Also, have your mountings (prongs, etc.) checked for security at the same time.
When not being worn, diamond jewelry should be stored individually in a soft cloth pouch to prevent scratching.
Avoid sharp blows when wearing your diamond jewelry, as diamonds can be damaged.
Everyday care should be taken to protect your diamond jewelry from hair spray, household chemicals and chlorine. These chemicals can build up and dull the surface of a diamond.
