Tourmaline It is usual to find different colourings in the same stone. The dark, black/greenish or azure stones are ferric tourmalines. If the tourmaline is translucent, brown, blue, green or colourless, it's poor in iron. The tourmaline has always been considered a carrier of many virtues. As all the gemstones, it canalises the energy, attracting the positive and neutralizing the negative one. It's very useful for those who are tired, in trouble, or trying to make some changes in their life. It also helps in improving situations of crisis. Physically, it benefits the tranquility, and brings health. Also makes self-regulation easier, so it's useful for meditation.
Pyrite Its name comes from the Greek "pyr" (fire). It sparks when it's clashed against other metals. It has a cubic crystallization; it can be found as an octahedron or dodecahedron crystal. In the ancient Egypt was already known its protective power, and it was used as an ornament in the priests vest, in necklaces or in religious images. It is especially appropriate for business, studies and communication. It is useful to carry one piece in the pocket or close to us for protection against negative energies.
