Geodes
A geode is a hollow rock lined with crystals, formed when mineral-rich water slowly filled a cavity and crystallized over time. Crack one open or cut it in half and you’ll find sparkling druzy, quartz or amethyst inside. Shop amethyst geodes, cathedrals and caves, pink amethyst geodes, agate and chalcedony geode halves, clear quartz geodes, geodes on stands and geode bookends. For kids and parties, choose break-your-own geodes in sets of 10, or pre-broken pairs. Statement amethyst geodes are one-of-a-kind and photographed individually. Some druzy geodes are dyed or have an aura (titanium) coating, and each listing says so.
