About Spertiniite
Francesco Spertini
Formula:
Cu(OH)2
Colour:
Light blue, blue-green
Lustre:
Vitreous
Specific Gravity:
3.93
Crystal System:
Orthorhombic
Name:
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).
