The best thing you can do to take care of your pearls is – WEAR THEM.
The oil from your skin helps stop the pearls from drying out and losing their lustre.
Sometimes for the same reason it is a good idea to have a little play with your string of pearls and hold them in your hand…so that the oils from your hand give them some care.
During the rest of the time when you are not wearing them, pop them into a soft pouch and lay them flat.
Make sure, as usual with any of our good jewellery, that they are not exposed to moisture.
