Druzy chalcedony forms through a process known as crystallization in cavities or on surfaces within rocks. Chalcedony itself is a microcrystalline variety of quartz composed of very fine quartz crystals.The formation of druzy chalcedony begins when silica-rich solutions percolate through rock cavities or fractures. These solutions contain dissolved silica and other minerals. As the solutions move through these spaces, they deposit silica on the walls of the cavities. Over time, the silica molecules arrange themselves into tiny crystals
