Claudio Albertini
Formula:
Fe2+(SO3)·3H2O
Colour:
colorless to yellowish
Lustre:
Vitreous
Specific Gravity:
2.458 (Calculated)
Crystal System:
Monoclinic
Name:
Named in 2015 by Vignola, P. et al. in honour of Claudio Albertini (1 June 1950 - 11 June 2018), an Italian mineral collector and expert in the systematic mineralogy of the Alps and pegmatites. Claudio Albertini is author of several papers in journals for mineral collectors and mineralogists, and he is author of the volume “L’Alpe Devero e i suoi minerali” on the worldwide famous locality of Mount Cervandone.
Stoichiometrically similar to gravegliaite (Mn-dominant), but not analogous due to structural difference. One of a very few natural sulphites, by hannebachite, orschallite, and scotlandite.

Compare some unnamed intermediate/mixed-valence S species from carbonate-hosted Zn-Pb deposits: Unnamed (Fe Sulphite) (an anhydrous counterpart), Unnamed (Zn Sulphite); UM1995-34-SO:Fe, UM1995-35-SO:FePb, Unnamed (Fe Subsulphite), pyrosulphites (Unnamed (Fe Pyrosulphite)), and sulphoxylanes (Unnamed (Fe Sulphoxylane)). You may also want to compare with Unnamed (Fe Oxysulphide).
