Geode

A geode (pronounced JEE-ode) is a rounded rock with a hollow interior lined with crystals, or containing other mineral matter. They are formed within sedimentary or volcanic rock, often from gas bubbles or other irregularities in the surrounding rock. Over time, mineral-rich water percolates through the rock and deposits layers of crystals, such as quartz, amethyst, or calcite, within the hollow space. These crystals grow inward from the walls of the cavity, creating the beautiful and often colorful formations that make geodes so prized by collectors. The outer shell of a geode is typically a hard, durable material like chalcedony, while the interior holds the true treasure. They can range in size from a few centimeters to over a meter in diameter. Finding geodes involves breaking open the outer shell to reveal the crystal interior, offering a glimpse into the hidden beauty beneath the surface.
