Jewelry Care - General Do's and Don'ts
Tarnish occurs naturally when certain metals are exposed to air and moisture. Since tarnishing is a natural process, it will happen eventually. However, you can slow the process down by keeping your jewelry away from humidity, chemicals, hair spray, and perfume, so put on your jewelry after your perfume.
Try to keep your jewelry out of the bathroom, shower, kitchen and hot tub. It also helps to store your jewelry in plastic bags with non-tarnish jewelry paper.
Chlorinated water can damage and ruin your jewelry, so remember to remove all jewelry before going near any chemically treated water (i.e. the pool at your gym or any other pool).
Remember the golden rule of jewelry: last on, first off!
