Zeolite Sculpture 50 (2.563kg)
Natural Zeolites come from volcanic rocks, ash layers, and alkaline ground water. This combination crystallises for thousands up to millions of years after being deposited in these environments. The results are naturally occurring Zeolites.
Zeolites usually occur in a matrix form with other crystals. These crystals often include Stilbite, Prehnite, Pectolite, Okenite, and Apophyllite.
