AI overview
Chalcedony is a type of mineral made from extremely fine mixtures of quartz and moganite, both forms of silicon dioxide, that are so tiny they can't be seen individually with the naked eye. It's composed of the same basic material as regular quartz, but has a different internal structure due to the way these two mineral components are interwoven together.
