Ownership of Opal The fact that the crystalline structure of this stone is amorphous can tell us a lot about its nature. In fact, it has no structure because the training process took place very quickly. By postulating that the eight crystalline structures correspond to eight types of human personality, lifestyles or archetypal energies, we come to the conclusion that the amorphous crystalline structure transmits an energy without time or space, chaotic and without structure. It is the Source from which everything derives, the sea of ​​possibilities, the unlimited creativity, the Inner Vision that transcends this dimension. According to modern crystal therapy, Opal stimulates the joy of living and helps you "see your life in color". It makes you emotional, seductive, unconventional and strengthens the sexual energy.
