We guarantee that these geodes
will have a hollow pocket inside. We also
offer pre-cracking service for a small fee. We use a special tool to snap them cleanly in half. You can break
your own geode by placing it in a sock and
lightly tapping it with a hammer. Be careful and always use
protective eyewear (safety glasses), adult supervision is required, recommended
for children ages 8 and up.
were once bubbles in lava. Over time mineral rich thermal waters
penetrate the bubble
as the water cools crystals begin to form within. The type of crystal
that forms inside of a geode is dependant on which
minerals penetrate the bubble at the time of
formation. In the case of the Las Choyas Geodes (aka Coconuts), a vast amout of different minerals
were present during formation making it difficult to predict what crystals you can find inside. It's a surprise every time one is opened.
