Rarities from the Paulo Matioli Collection
May 20, 2015 - We’re thrilled to be premiering Paulo Matioli’s collection of rare fine minerals in this first of many updates! It is both a systematic and Brazilian/worldwide rarities collection. The complete collection consists of approximately 1,200 pieces and represents about 950 mineral species. Several lots have already been sold to the Smithsonian, British Museum, American Museum, and other notable institutions. There are hundreds of rare and unusual species available. The premier pieces will be presented here in the rare minerals gallery, and others will be listed intermittently in the mineral auctions.
Paulo Matioli received his master’s degree in geology from the Geoscience Institute at the University of Sao Paulo and is beginning work on a doctorate in mineralogy under his advisor Dr. Daniel Atencio. In addition to participating in the characterization of multiple mineral species, including Footemineite, he also collected the only known sample of Brumadoite, and the first specimens of Matiolite, a secondary pegmatite phosphate mineral named in his honor.
All of the specimens in this update are from his collection, many via other important collections and collectors as noted by the labels, and other forms of information provided. There are several important specimens from the geologically and mineralogically diverse Mn-Fe deposits at Langban, Sweden.
