Keep your precious jewelry pieces in a fabric lined jewel case or box with compartments or dividers. Don't jumble your diamond pieces in a drawer or jewelry case, because diamonds can scratch other jewelry and even scratch each other.
Diamonds get smudged, soiled and dusty. Lotions, powders, soaps, even the natural skin oils, put a film on diamonds and cut down their brilliance. Chemicals in the air can discolor the mounting of precious jewelry. So, clean your diamonds regularly.

Commercial jewelry cleaner, or a mix of ammonia and water, or mild detergent will do the job well. Dip the jewelry in the solution, scrub gently with a soft brush. (Be sure to brush between and underneath the prongs). Rinse in clear water and dry with a lintfree cloth.

Don't wear your diamond engagement ring while doing rough work. Even though a diamond is durable, it can be chipped by a hard blow. Don't let your diamond come in contact with chlorine bleach when doing chores. It can pit and discolor the mounting.

Do see your jeweler at least twice a year and have your jewelry checked for loose prongs and wear of the mounting. The Prospector can also give your jewelry a professional "shine up" at the same time.
