Blue topaz is a mineral that typically forms in igneous and metamorphic rocks. It crystallizes from hydrothermal fluids or in pegmatitic environments, where high temperatures and pressures allow for the formation of large crystals. Over time, the rock cycle can expose these rocks to weathering and erosion, breaking down the minerals and transporting them to sedimentary environments. Thus, blue topaz can be found in both igneous and sedimentary contexts within the broader rock cycle.
