\Usually geodes (or their counterparts, nodules) can be identified by their shape, weight and texture. Many geodes are round or oblong and somewhat heavy for their size. The outside of a geode or nodule is usually worn down and resembles a head of cauliflower. Many geode crusts are limestone and may have a dull tan or brown coloration. But as for actually knowing if it is a geode by just looking, it is a probably a 70 percent chance of being correct.
A geode typically cleaves or breaks along its crystal boundaries, revealing the inner cavity lined with crystalline structures. The cleavage of a geode can vary depending on the type of minerals present and the specific conditions under which it formed.
It sounds like you are describing a geode, which is a rounded rock typically with a hollow cavity lined with crystals. Geodes are formed in sedimentary or volcanic rocks and can contain various types of minerals such as quartz, amethyst, or calcite.
Geode is the scientific name. It is derived from Greek and means "earthlike."
A geode with flint inside would be a type of geode that contains the mineral flint, a hard, sedimentary cryptocrystalline form of the mineral quartz. Geodes are typically round rock formations that contain hollow cavities lined with crystals or mineral deposits, and finding flint inside one would be an uncommon but interesting occurrence.
A geode typically has a vitreous luster, meaning it appears shiny like glass. The streak of a geode is usually white or colorless because it is made up of crystallized minerals like quartz or calcite. Geodes have a hardness of around 7 on the Mohs scale due to the presence of minerals like quartz.
Geode is a rock or stone with crystals.

A geode is a hollow stone found on the earth that is lined on the inside with crystals.

The word you're looking for is.... stone.
It is a geode. Geodes form in gas bubbles in cooled porous lava flows. Groundwater provides the minerals that crystallize inside these hollow bubbles. Eventually erosion removes the lava rock that provided the mold that shaped the outside of the geode and then humans find them (and usually cut or crack them open to look at the crystals inside).
