AI overview
Agate is a semi-transparent, banded stone made of chalcedony that comes in many varieties and can be found worldwide in nature. People value agates for their distinctive colored bands and decorative appeal, though the term is sometimes loosely applied to similar-looking stones that aren't technically true agates.
