If your favorite pearl strand necklace is getting a little dull, don’t use ammonia-based jewelry cleaners to clean them. Pearls are delicate ans ammonia can strip the nacre, the shiny outer part. To make them glossy again, put a few drops of olive oil on a soft cloth and buff each gem. The olive oil removes dirt and renews the pearls’ moisture level, which is responsible for their luster. Olive oil indeed is not just a kitchen staple, I’ll be posting more of its brilliant uses on my future posts.
