Stones with crystals inside are called geodes. Geodes are natural rock formations that contain hollow cavities lined with crystals, often quartz or amethyst. They are often cut or broken open to reveal the beautiful crystals inside.
Geodes are hollow rock formations that contain crystals inside. They are typically formed in sedimentary or volcanic rocks where mineral-rich water accumulates in cavities and deposits crystals over time. Geodes are commonly used for decorative purposes and as collectible items.
Large crystals in a mineral specimen typically form when the mineral has enough time and space to grow without being obstructed by nearby crystals. This often occurs in environments with slow cooling rates or low levels of impurities, allowing the crystals to grow to a considerable size.

Mica minerals often appear in 'books' which are stacks of sheet-like mineral crystals.
Geodes are rocks that are lined or filled with crystals. Pegmatites are rock formations that often exhibit extremely large crystals. Just a note--all rocks are composed of mineral crystals, with few exceptions. The crystals in some, however are just too small to see.
