Crack the uninteresting, dull exterior of these geode rocks, to reveal a sparkling cluster of crystals! This is a very exciting and educational exercise for any gemstone enthusiast as well as kids.

The most effective way to break open this rock is to use a hammer and very lightly tap it, this should cause it to crack in two or more pieces.

Tools for opening are excluded. You are purchasing one closed geode rock, guaranteed to crack open to Agate or Quartz crystals.
