Yavapaiite
Grotta dell'Allume, Faraglione Nico, Faraglioni di Levante, Porto Levante, Vulcano Island, Lipari, Eolie Islands, Metropolitan City of Messina, Sicily, Italy
Sphere of pale purple, thick tabular, interpenetrating crystals of yavapaiite.
Note that coquimbite is also present on the specimen, but with a typical barrel-like, trigonal morphology.
The child photo shows another aggregate of yavapaiite, with tabular crystals, a little thick, and here, in all evidence, they are elongated.
