Definition: Crystallogenesis is a process in which minerals, such as quartz and feldspar, are metamorphosed into different forms of crystals. These metamorphisms can result in the formation of new minerals or even new types of crystals that were previously unknown. The process itself is not always easy or straightforward, and it often requires specialized equipment and techniques. It involves heating and cooling processes to melt and cool the mineral, followed by a phase change from solid to liquid, which then forms a crystal.
