A geode.
A rock lined with mineral crystals is called a geode. Geodes are hollow rocks that contain a variety of different crystals inside, such as quartz, amethyst, or calcite. These crystals form inside the geode over time as mineral-rich water flows through and deposits minerals along the walls.

These small crystal-lined spheres are called geodes. They form when minerals crystallize inside a cavity within the limestone rock.
Quartz is a mineral that commonly exhibits striations on its surface. These are often caused by growth patterns during its formation, giving it a lined or grooved appearance.
A hollow space in a rock is called a vug or a vuggy. It is typically formed when minerals dissolve or are weathered away, leaving a cavity within the rock. Sometimes, vugs can be lined with crystals or other minerals.

A crystal-lined rock is commonly referred to as a geode. Geodes are spherical rocks that contain a hollow cavity lined with crystals, typically formed in volcanic rocks or sedimentary deposits.
A rock lined with mineral crystals is called a geode. Geodes are hollow rocks that contain a variety of different crystals inside, such as quartz, amethyst, or calcite. These crystals form inside the geode over time as mineral-rich water flows through and deposits minerals along the walls.
A crystal-lined rock is called a geode. Geodes are hollow rocks that contain sparkling crystals inside, formed by minerals depositing in the cavities of the rock over time.
They're called geodes. Basically, they're cavities in the molten material (magma) in the form of gas bubbles. The mineral rich solution seeps in and crystallizes and grows until all the solution is exhausted. That's why sometimes you'll end up with a crystal filled cavity and other times the whole void is filled in with interlocking crystals.

It is a hollow organ, the walls of which are made of tissue that is lined with muscle.
