Agate
Agate is a fine-grained variety of chalcedony, a type of microcrystalline quartz. It's known for its concentric color banding, often with variations in shades of white, gray, and brown, but also blue and green. Agate forms in cavities within volcanic rock, where silica-rich water deposits quartz crystals layer by layer.
