Cleaning your jewelry regularly can keep it looking good and lasting a long time. Most colored gemstones can be cleaned with warm water, mild dish soap (no detergents) and a soft brush. Be sure to thoroughly rinse your jewelry to remove cleaning solutions.
Rubbing alcohol works well, but bleach does not, and can literally destroy jewelry, so avoid using it. Soft gems, such as pearls, on the other hand, can easily scratch. Use a clean makeup brush and warm, soapy water to gently clean them.
Remove jewelry during tasks – When performing manual tasks, remove your jewelry to prevent physical damage or exposure to chemicals or cleaning fluids. Some tasks should be avoided when wearing jewelry include kitchen work, gardening, cleaning the house, showering and other common tasks.
Don't wear jewelry in swimming pools or spas – chlorinated water can react with the metals found in jewelry causing color changes and even structural damage. As a result it's a good idea to remove jewelry before entering the pool or spa.
Contact sports and jewelry don't mix – Hard blows during sports can damage jewelry not to mention the people involved. All jewelry should be removed before play begins.
