Often used as talisman, stones are a symbol of protection, healing and love. The symbolism associated with minerals depends mainly on their colour, composition and crystallisation. In lithotherapy, each stone is symbolically linked to a specific part of the body to promote its healing. Stones are also a symbol of love, sincerity and eternity and are used to celebrate wedding birthdays. According to astrologers and alchemists, each stone is connected to an astre and corresponds to one of the 12 signs of the Zodiac. Whether in the field of medicine, marriage or astrology, the stones and their symbolism have always accompanied humans.
