“A geode of 5 cm x 3.5 cm is full of beautiful phosgenite crystals, centimeter-sized and shiny. This parent photo represents an aggregate of some of these crystals, showing the particular and rare symmetry 422. See the book "The Wonderful World of Crystals" written by Dr. Carlo Maria Gramaccioli, Edizioni Calderini, 1986, page 208. The first child photo more closey illustrates the same aggregate and the third child photo provides an overall picture of the geode. Collection and photo of Gianfranco Ciccolini.”
