Ways to take care of your jewelry
Keep It Dry
The fastest way to tarnish your jewelry is by contact with moisture and liquids. This includes putting on lotions, washing your hands, a spritz of perfume, and sweating with your jewels on. Even the oils on your skin can wear down the plating and metals over time - and this will again vary from person to person. Get your jewels wet by accident? Be sure to wipe and dry them off right away!
Store It Properly
Take it up a level by storing your jewels in a Ziploc bag - but you'll want to make sure you get rid of as much air as possible before sealing it. With the air removed, the metal won't be able to oxidize from the air.
