Crack open these real geodes to discover how stones are formed! People of all ages will love the surprise of beautiful crystals hiding inside an unassuming rock.
Geodes are created in the hollow areas of soil such as animal burrows or tree roots. They are also formed in the bubbles in volcanic rock. Over time, dissolved minerals seep into a hollow area and harden into an outer shell creating the geode. The minerals continue to form on the inside walls of the shell, growing towards the center. The most common dissolved mineral is quartz but amethyst and other minerals ca also be found. These small geodes are composed of various forms of quartz. The inner core is commonly the crystalline variety of quartz while the outer skin is made up of microcrystalline quartz or agate. Discover what treasure lies in your geode when you crack it open!
