Tourmalated Quartz is clear rock crystal (crystal quartz) which has grown together with black tourmaline, and shows strands of the tourmaline running through the quartz, hence "tourmalinated." The earliest use of tourmalinated quartz was for tools made by hominds in Ethiopia over 2 million years ago. Tourmalated Quartz is believed to protect the wearer from negative thoughts and emotions. It is said to be filled with energy that flashes through it and connects one with other fields of energy. Tourmalated Quartz is thought to provide a balancing of yin/yang energies and release negative patterns. It is used by some to treat disorders of the digestive tract and to detoxify the body. Tourmalinated quartz is aligned with the Zodiac signs Libra, Capricorn and Scorpio. It is associated with the 6th, Third Eye or Brow Chakra, but is also believed to be effective on the secondary chakras of the hands and feet, including the meridians. Although it can be found in many parts of the world, tourmalated quartz used for jewelry-making comes mostly from Brazil. Quartz is the best-known piezoelectric gem--it can carry an electrical charge when exposed to an applied voltage, in response to pressure or in response to mechanical stressors. Quartz is also a pyroelectric gem--able to generate an electric charge through rapid states of temperature change. These are the scientific qualities behind reliable and accurate quartz movements in watches. The same properties mean it is ideal for use in microphones, speakers, filters and sonar.
