Also referred to as Amethyst Churches or Amethyst Geodes, these Amethyst Cathedrals are imported directly from the Brazilian state of Rio Grande do Sul, in the Eastern Atlantic Coast of the country.  Amethyst Cathedrals are one of the most unique gemstones created by nature.  Each specimen is special whether it includes extra-deep colored purple tones, citrine crystals, or their unique shapes and are sure to enhance the appearance of just about any landscape, store design, or home decor theme.
