Each geode is approximately 2.50 inches in diameter.
Guaranteed to be Hollow with Crystals - 95% of these geodes contain quartz crystal linings that can range from a smoky, brown, light blue, lavender, clear or 5% a good quality purple amethyst. The majority is a varying shade of smoky quartz and contains a brown siderite or agate rim. See sample opened geodes for typical interiors (samples are not included with your purchase).
Possibility for Additional Minerals - About half have Calcite and/or Goethite, 5% are filled with white feathery Mordenite that usually has Calcite as well.

Great idea for a school science project, birthday party, or just something to entertain your kids (or yourself!) with. We will provide opening instructions and an information card about the geode(s) you receive. Again, we guarantee these geodes to be hollow and to have crystals - there is no guess-work with our geodes - if you receive a solid geode, we will send a replacement at no cost to you and we pay the postage costs.
