Phillipsite-Na specimen

Phillipsite-Na Locality: Palagonia , Northern Iblean plateau, Catania Province , Sicily , Italy ( Locality at mindat.org ) Size: small cabinet, 5.6 x 3.4 x 1.8 cm Phillipsite (rare zeolite) This is a fairly rare member of the zeolite family that at times can have calcium, or potassium, or sodium as its chief constituent. Phillipsite has cemented brecciated rock and formed a series of botryoidal groups, the largest of which measures 1.0 cm across. These spheres are snow white, and lustrous. I am told it is quite good for the locality! — Photo: Robert M. Lavinsky · CC BY-SA 3.0
