To be sure your diamonds always sparkle, it is important to clean them periodically. Here are some recommended methods.

Professional Cleaning
This is the best option. It’s also important to have your jewelry checked occasionally to make sure prongs haven’t bent or weakened.

Mild Liquid Detergent
Soak your jewelry in a small bowl warm, sudsy water made with any mild liquid detergent. Gently brush the diamond jewelry with a soft toothbrush while it is in the suds. Then, rinse each piece under warm running water. Pat dry with a soft, lint-free cloth. Make sure to always stopper your sink.

Household Ammonia
Place the jewelry in a small bowl containing a half-and-half solution of ammonia and cold water for thirty minutes. Lift out and gently tap around the front and back of the mounting with a small soft brush. Swish in the solution a second time, rinse and drain on tissue paper.

Jewelry Cleaners
Use any brand name liquid jewelry cleaner and follow the instruction given on the label.

Vodka on the Rocks
No one is sure how it was actually discovered, but it is safe to say that at some point someone took the idea of a "vodka on the rocks" literally and discovered an imaginative way to clean their precious diamonds. Simply let the diamond soak in a glass of vodka. Preferably one you do not intend to imbibe.
