Crazy Lace Agate is a variety of chalcedony, which is a microcrystalline form of quartz that's infused with iron and aluminum and is often brightly colored and complexly patterned. Crazy lace agate is formed when layers of silica-rich ash and lava are deposited on top of each other. Over time, these layers are compacted and cemented together, forming a hard rock. The different colors and patterns in crazy lace agate are due to the presence of different minerals in the original ash and lava.
