Keep your fashion jewelry dry and clean
Whether it's a necklace, ring, bracelet or earrings, exposing fashion jewelry to any type of cream, chemical product, lotion, perfume, oil or even water is an undeniable accelerator of tarnishing. Metals will oxidize & see their color changing & jewelry silver or gold platings will chip. So make sure to always remove your jewelry before applying cream, perfume or even when you wash your hands.
Wear your costume Jewelry occasionally
Don't forget to give your costume jewelry a little break from time to time. Fashion jewelry is usually not meant to be worn every day. Therefore, if you wear the same piece of jewelry on a daily basis, you might see discoloration coming quickly. To preserve the life of your jewelry, change it as often as possible by varying the outfits. As they are pretty affordable, do not hesitate to buy for example 2 or 3 fashion necklaces in the same style & alternate them.
Always clean your fashion jewelry after wearing
Another tip to make your costume jewelry look its best as long as possible is to clean them after each use. This may seem a little laborious, but it's actually very useful to see your jewelry last! Some soap, oils or perfume may have accidently gotten on your skin while you wear your ring, earrings, necklace or bracelet. So wipe them down with a soft cloth to remove any product residues & sweat that accelerates oxidation.
