When you buy pearl jewelries from LuckPearl, you're buying an heirloom that will, hopefully, last for generations. In order to ensure that your fine pearl jewelry stays beautiful, it's important to take care of it in the right way. Here are some tips for preserving the beauty of your pearls. 1) Do not use toothpaste to wash your freshwater pearls. Toothpaste contains tiny abrasive fragments that can damage your pearls and affect their surface quality. The best way to wash pearls is to use water or soap specially formulated to be gentle, such as baby shampoo. 2) Avoid frequent touching. Our body, especially our fingers and hands, may probably be sweating and produce oil and sweat that can coat the pearls if you touch them too often, masking their luster and glow. 3) Don not wear them constantly. Take off your pearl jewelry when performing any strenuous tasks that may get you sweating. Don't wear them while swimming or taking a shower. 4) Don't put them in washing machine. Yes, we've heard of people doing this. Pearls can't stand shaking - so don't let them go through the washing machine. 6) Put on your pearls after you dress. Your pearl jewelry could catch on clothing, and pearls can be damaged by stiff materials in clothes. 7) Bring a pearl bag. Most of our time, we wear our pearl jewelry - just because there's nowhere safe to put it. Keep a small cloth bag for your pearls in your purse. That way, if you need to take off a pearl ring to wash your hands or remove your earrings to go swimming, you can have a safe place to keep your pearls. 8) Perform regular maintenance. Check your pearls regularly to make sure none have come loose. Clean them using a soft cloth and mild soap. If you wear a pearl necklace often, we recommend having it restrung once a year. A knot should be tied between each pearl in the strand, to keep scratches and abrasions from the pearls rubbing against each other to a minimum.
