Green Aventurine
Quartz & Crystal Family
Green aventurine is a quartzite containing many tiny, aligned mineral flakes. Chrome-bearing fuchsite mica gives the usual green color and creates aventurescence, the glittering reflections seen as the stone or light moves; it is a rock, not a single quartz crystal.

Its name comes from Italian a ventura, “by chance.” The term first referred to sparkling aventurine glass associated with an accidental discovery in early eighteenth-century Italy, then passed to natural stones with a similar glittering appearance.
