Store your jewelry in a dark and dry place when you are not wearing it.
Keep each piece separately to prevent scratching and tangling. Keep the original packaging.

Take your jewelry off while showering and back on after you have put on your body lotion and perfume to avoid staining.

Whilst our jewelry derives from nature, it will prefer not to go swimming with you.

Last but not least: WEAR IT. Wearing your jewelry will protect it from attaching little dirt particles because of the natural friction.
