Small Spectacular Amethyst Geode CathedralThis beautiful Amethyst geode cathedral rock specimen is in natural form and has a polished edge. This Amethyst comes from Brazil and can be found in volcanic rock or Basalt. These amethyst geodes form by gas bubbles that were rising to the surface but became trapped because the lava cooled too quickly. Then cavities form as the lava hardens around the bubble. The size of this Amethyst cathedral is perfect for the budget conscious buyer. Don't miss
