Insight into the formation of rock crystal:
Rock crystal is formed by the cooling of silicate melts. These melts contain silica (SiO₂) and other minerals. During the cooling process, the silicates crystallize and form quartz crystals.
Geological conditions: Rock crystal forms in cavities (veins, fissures, geodes) in rocks. Formation occurs under high pressure and high temperature. Silica accumulates in these cavities and begins to crystallize.
Timeframe: The formation of rock crystal can take millions of years. During this time, the crystal grows slowly, layer by layer.
