Pearl is thought to be the finest stabilizer of the emotions. It increases tolerance and flexibility, brings relaxation where there has been tension and frustration. Swedenborg wrote that pearls were truth, celestial and spiritual knowledge, faith and charity.
The pearl was the emblem of purity, innocence and peace. It was sacred to the moon and Diana. In ancient times it was worn by young girls and virgins on whom the protection of "Chaste Diana" was invoked.
