What is stone geode?

A stone geode is a geological formation that resembles a hollow rock with a cavity inside which is coated with mineral crystals. These geological formations are formed by mineral-rich liquids that have evaporated or by gas bubbles that have become trapped in volcanic rocks. Over time, mineral-rich water seeps into the cavity and deposits crystals on the walls of the geode. Common minerals found in geodes include amethyst, quartz, calcite, and agate. Stone geodes are often collected and used for decorative purposes or for their healing properties, as they are believed to have metaphysical and spiritual benefits. They can also be cut open to reveal the intricate crystal formations inside. Geodes can be found all over the world, but the most famous locations for geode hunting include Brazil, Mexico, Morocco, and the American Midwest.
