buy it in French Polynesia rather than anywhere else
Only few people are aware about technics that can alter pearls
natural colors, luster and even shape ! In French Polynesia
those technics are not yet used, pearls are simply cleaned
after harvest, that’s all. Your pearl is more authentic if it is not treated, for this reason it is even more rare nowadays, enjoy it !
How to take care of your pearls
DO NOT swim, shower or sleep with your pearls on.. Pearls are porous and thus may absorb detergents, fragrances, moisterizing cream, etc... . Be careful also not to spray perfume or hairspray on them. You should shine your pearls with a soft cloth regularly. To clean them, use a gentle fragrance free liquid soap and water, then swipe and shine them. If on a strand, only use dedicated special liquid onto your pearls, taking care not to wet the necklace thread
, then clean the pearls with a soft, dry cloth. I personaly use "Perfect Pearl Spray" from "Town Talk Polish Co.Ltd.". Never soak pearls neither in olive oil nor salt water, as this will alter the luster, and is potentially damaging if done often. (unlike most shops and websites advise!).
