There are two types of geodes: the volcanic, which begin as gas bubbles trapped in cooling lava; or sedimentary, which are created as rock weathers over time, creating hollow cavities. In both cases, mineral deposits carried by groundwater slowly seep into the empty space and eventually crystallize into a mesmerising combination of colours and crystals. Because no one agate has the same deposit of minerals as the next, every stone is unique. For this reason, every Karolin Van Loon creation is truly a one of a kind, a singular design that can never be recreated.
