I hand made each geode shown. In this listing you are choosing only 1 for the price shown. These are the last of the rock formation mold you see at 8"x6"x4". Each piece is unique and one of a kind. No 2 are ever alike. I can custom create a geode in any size, any shape, and any color scheme you like. The $100 price tag includes US shipping. Find these and more on all of my social media under @GeodeMaker
