Tips for general care - Even though you may wear your diamond engagement ring 24 hours a day, you should still give thought to its care. DON'T wear it when you are doing rough work. Even though a diamond is durable, a hard blow can chip it. DON'T let your diamond come in contact with a chlorine bleach when you are doing household chores. It can damage and discolor the mounting.
DO see your jewelers at least once in six months and have them check your ring and other precious pieces for loose prongs and wear of mounting. He'll usually give them a professional shine-up too.
At home, you can clean your diamond jewelry using one part ammonia and six parts water. Use gentle scrubbing with a soft brush to gently loosen any dirt. We recommend storing your diamond jewelry in individual soft-cloth pouches to prevent jewelry pieces from scratching each other.

Take care of your jewelry and it will shine for years. Each piece of jewelry is individual, but as a general guide the National Association of Goldsmiths advises:
Ideally a watch needs to be serviced every year or two (ask your jeweler about your particular brand and model). Some watches will keep going OK for years without needing repair, but don't risk it, there could be problems of wear building up that will make eventual overhaul more difficult or impracticable.
Unless the degree of water resistance is clearly defined or marked on your watch face or back cover or in the product manual, don't risk wearing it in the shower or pool. 'Water resistant' is not the same as 'Waterproof'.
No matter how handy you are, don't attempt any 'do-it-yourself' watch repairs or even take a peek inside. Only an expert watchmaker should be trusted to put your watch back into perfection.
