If you wouldn't put it on your skin you shouldn't put it on your jewelry. Avoid chemicals like household cleaners and liquid jewelry cleaner. All you need is a great polishing cloth. I love the Sunshine Cloth. You can also clean your stones with a soft toothbrush and water + a drop of dawn soap, then rinse under the faucet and dry with a soft cloth. Don't forget to plug the drain first!
Avoid letting pets & children play with your jewels.
Please don't wear them in the pool, as the chemicals with oxidized your metals. Try not to sleep, garden or work out in them either.
Store your jewelry in a dry place. Moisture leads to tarnish, the bathroom is not a great place to store your jewels.
To slow down the natural tarnishing process, we suggest a small ziplock bag if your are going to give your jewels a break for more then a few days.
