HOW TO CARE FOR YOUR PEARLS
Pearls, unlike any other gem, are produced by a living creature. Delicate as they appear to be, they should last forever if you follow these simple rules.
You can wear your pearls around your house and even in bed as the skin's natural oils give them a special lustre. Store pearls separately from diamonds that could scratch the surface of the pearl. The best idea is to put them in a cloth bag and tuck them away in a corner of your jewellery box.
Never ever, spray perfume directly onto the pearls as its acidic nature, and even hairspray, can erode the outer layers. And old make-up caked onto pearls is not a good look.
In the case of pearl necklaces, every five years or so take them to a jeweller to check if they need re-stringing. It is a small investment that will save you from that dreadful situation of scrabbling around on all fours retrieving the bouncing orbs from underneath people's feet and behind the sofa, and inevitably loosing some.
