colorless, white
Crystal System:
Named after its locality (Cerro San Cristobal, Mexico).
The cubic high-temperature polymorph of cristobalite, stable at temperatures above 1470°C (the transition is slow and the transition temperature difficult to determine; for a review see Heaney, 1994).
Found in volcanic environments. Specimens in collections are paramorphs of tetragonal α-cristobalite after β-cristobalite.
