Ageodeit is a rocky cavity, normally closed, lined with crystals (often automorphic) and other mineral matter. It is not really a mineral but a composition of magmatic, crystalline and / or sedimentary formations. Widely distributed throughout the planet, geodes are the main source of minerals in mineralogical collections because they are an optimal medium for various mineral formations.
The wordgeodecomes from the Greek γεώδης ( geôdês,’like the Earth’), itself formed by γῆ (guê,’Earth’) and ειδος ( eïtwo, ‘shape, aspect’). The fact that he refers to the rotundity of the Earth has led to a debate as to whetherdrusen(flattened cavities) could be classified as geodes.
Geodes are one of the most rewarding finds in a field search for minerals.
At first glance they look like simple stones with an unattractive appearance, but when opened they are a harmony and perfection of crystals.
