How to store your pearls
Take care not to store your pearls crowded in with other jewelry. They can become scratched by the metal or gemstones of the other pieces. Use a special area in your jewelry box or jewelry case for the pearls to be hung individually, or kept in their own pouch or bag made of chamois or other soft material.
It is recommended that fine pearl jewelry should be restrung periodically to assure that the silk or nylon cord holding them is in good condition, thus better protecting the piece from possible breakage and ultimate loss of the item.
Keeping in mind that pearls need gentle care, are relatively a fragile gem, easily scratched. But with care they can last to be treasured heirlooms for generations.
