It's so delightful to collect Banded Agates. Each one is unique and like a little work of art. And Banded Agate jewelry is also fun to collect.
Also called Banded Agate stone because an agate is not just one sole mineral, but a composite of minerals such as chalcedony or some other form of cryptocrystalline and micro-fine quartz particles. It formed in layers, which are the bands, usually alternating between a layer of chalcedony and a layer of quartz.
