Pure silicon dioxide (SiO2) in various forms. Crystalline quartz is the most common, but silica also forms as chalcedony (microcrystalline) and opal (amorphous).

💡Amethyst, citrine, rose quartz, and smoky quartz are all just quartz with different trace impurities. Heat-treating amethyst turns it into citrine.
