Although it is durable, a diamond can still be chipped. It is best to take off your diamond jewelry when doing strenuous activity or working with your hands. - Take off your diamond jewelry while sleeping; a prong can catch on the sheets and bend, causing you to lose your diamond. - Though most harsh chemicals are not going to damage your diamond, many (like chlorine) could damage or discolor the setting and cause your diamond to fall out. - Have your diamond jewelry checked out once a year to make sure everything is fine; one bent prong could mean your diamond is gone forever.
