Simone Citon is a mineral dealer in Italy who really wanted a particular piece of rhodochrosite (listed on this site) in my father's collection. We arranged a trade: That one piece in exchange for a collection of small minerals representing all (or almost all) the elements. Since the rhodochrosite belonged to my father he's listed as the contributor of all the minerals from Simone.
