amethyst crystals - The violet to purple amethyst is the most important and best known gem variety of quartz and has been used for lapidary works since ancient times. Today most amethyst comes from Brazil and Uruguay. Before these resources were discovered, most amethyst was mined in Sri Lanka, India, Germany (Idar-Oberstein region), and the Ural Mountains (Murinska gem region) in Russia.
