Geode

A geode is a type of rock that looks like an ordinary rock on the outside, but when you break it open, it reveals a hidden treasure of sparkling crystals inside. Geodes are formed when minerals such as quartz or amethyst form in the cavities of volcanic or sedimentary rock.
The crystals inside a geode can take many different forms, including clusters, points, and druses. They can come in a variety of colors and are often highly prized by collectors for their beauty and uniqueness.
Geodes are often used in meditation practices and in interior design as natural decorative pieces. They are also popular among collectors, who enjoy the thrill of breaking open a geode to reveal the hidden crystals inside.
Overall, geodes are fascinating and beautiful natural wonders that offer a glimpse into the incredible diversity of the Earth's geology.
