About SpertiniiteHide

Francesco Spertini
Light blue, blue-green
Specific Gravity:
Crystal System:
Named after Francesco Spertini (b. 1937), chief geologist, Jeffrey mine, Richmond County, Québec, Canada, the discovery locality.
Chemically similar to anthonyite. Also compare 'UM1974-06-O:CuH'.

In terms of chemistry alone it is the Cu analogue of wülfingite, which is also orthorhombic but has different space group (different structure anyway).

Classification of SpertiniiteHide

Approval year:
First published:

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
F : Hydroxides (without V or U)
D : Hydroxides with OH, without H2O; chains of edge-sharing octahedra

2 : X(OH)2

7 : Oxides and Hydroxides
3 : Oxides of Cu
