Geodes turned Marc on as a kid and still do! Geodes begin to form as mineral-rich water trickles into a rock’s porous surface. Tiny crystals are left behind as the water evaporates. As millions of years pass, the evaporating water gradually builds crystals inside the empty space. Each crystal formation takes its colors from the iron, magnesium, sulfur, or other minerals in the water.
And oh, the colors and gems that lie inside – awaiting unearthing! Marc’s geode collection hails from all over the world. Come explore it!
