Amethyst is the birthstone for those born in the month of February, and also is the 6th anniversary stone. Throughout history, Amethyst, along with rock crystal and other quartz stones, was believed to have supernatural powers. Amethyst was known to prevent drunkenness and protect the wearer from catching contagious diseases. Spheres of rock crystal were also believed to possess powers that could foretell the future.
This might have developed from the fact that quartz does posses properties that make it seem magical. Quartz crystals become electrically charged when subjected to pressure, and if an electrical current is run through a piece of quartz, the crystal will vibrate at a single, constant frequency, which in turn is determined by the strength of the current and the thickness of the crystal. For this reason, quartz crystals are commonly used to regulate watch movements and stabilize electronic frequencies in radios.
