A geode,(I bielive)
Geodes are hollow ball-like objects found in sedimentary rocks that contain quartz crystals. These formations are typically created through the deposition of minerals within cavities in the rock over long periods of time. Geodes are often prized for their unique and beautiful crystal formations.

Geodes. They can be found in some igneous rocks as well. They start as a hollow cavity created by a gas bubble or decaying organism. Mineral rich water seeps into the cavity and crystals form from the outside toward the inside.
The hollow ball-like objects are called geodes. Geodes form when minerals are deposited inside cavities in sedimentary rocks, such as limestone or shale. The outer shell of the geode is typically made of chalcedony, while the interior can contain various minerals like quartz, amethyst, or calcite.
These hollow ball-like objects are known as geodes. Geodes form in sedimentary or volcanic rock cavities when minerals such as quartz, calcite, or amethyst crystallize inside the cavity over time. They often have a plain or dull outer surface, while the inside is filled with colorful crystals.
Those ball-like objects are known as concretions and they form when minerals precipitate around a central nucleus. In the case of quartz concretions, silica-rich fluids flow through sedimentary rock layers and deposit quartz around a nucleus like a shell or fossil, forming the spherical shape. Concretions can come in various sizes and shapes and are often found in sedimentary rocks.
Its a Geode. :) ~Hope it helped!~

Sedimentary rocks form from the accumulation of sediment and can be found in various objects on Earth, including natural features like cliffs, riverbeds, and canyons. They are also used in construction materials such as limestone and sandstone for buildings and roads. Additionally, sedimentary rocks can be found in everyday items like cement and certain types of bricks. Fossils, which are often preserved in sedimentary rock layers, also provide significant insights into Earth's history.
