geodes
A geode is a hollow, rock-like formation that often contains crystals or mineral deposits inside. Think of it as a rounded shell, usually from volcanic or sedimentary rocks, with a cavity lining that can be lined with beautiful crystals such as quartz or amethyst. Geodes start as bubbles or cavities within rocks, which later fill with mineral-rich solutions. Over time, minerals crystallize on the inside, creating the vibrant, sparkling interiors. They are prized for their striking appearance and are commonly used in jewelry and decoration. Geodes showcase the natural process of mineral growth within a protective outer shell.
