The sign of the Virgo, ruled by Mercury, is associated with opal stones and mostly gray. The Sapphire is the stone of the Virgin, which helps in love and healing from disease and inner problems. In terms of memory and intuition is highly recommended to use the Malachite, which will also bring rationality, self-confidence and make you pass insecurities and fears. At the physical level are recommended instead Rutilated Quartz or Agate. The first fights physical and mental fatigue, and the second is a great natural energy.
