About Albertiniite
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. The true analogue is mikenewite.
One of a very few natural sulphites, by hannebachite, orschallite, and scotlandite (i.a.).
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).

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
