To find out if a pearl is real, you can lightly rub them against each other. If they are real, they will feel gritty as they are formed with calcium. If they are synthetic, they will feel slippery. You can also try to rub them against your front tooth if there is no other pearl to rub agains it. We suggest that you KINDLY ask someone if you can tooth test their pearls first. Someone might be very protective of their pearls and you could cause harm to the skin, especially if they are very old.
