Iceland is called 'The Land of Ice and Fire' for a good reason. The glaciers and cold climate mixed with volcanoes and geothermal activity is undeniably an interesting combination. There is seldom eruptions, but activity is going on all the time. Nature is for real up here, in all its mystery, which you will see when you travel here.

Erupting volcano - Most of the geodes that we find today were actually created when ancient Volcanoes erupted! As the lava cooled, air bubbles became trapped inside creating empty pockets. Over millions of years these pockets filled with the minerals which hardened into the beautiful crystal treasure we find today!
