a geode. They're fairly common, but often very pretty.
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 often lined with quartz.
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.
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.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
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.
Geodes are typically millions of years old, formed when minerals crystallize within a hollow cavity in rock like a volcanic bubble or sedimentary rock. The age of a geode is determined by the formation process that creates it, so they can range from hundreds of thousands to millions of years old.
