Geodes are geological rock formations which occur in sedimentary and certain volcanic rocks. Geodes are essentially rock cavities or vugs with internal crystal formations or concentric banding. The exterior of the most common geodes is generally limestone or a related rock, while the interior contains quartz crystals and/or chalcedony deposits. Some geodes are completely filled with crystal, being solid all the way through.

  • Sizes vary from 2 to 3 inches (60-70 mm).
  • Crystallization and  the shape of each geode varies.
