Serpentina verde di Sardegna, from Sardinia, Italy
Geological description:
Serpentinite with hints of coarse-grained peridotite microstructure evident in dark domains. Contains scattered crystals of pyrite and disseminated flecks of pale yellow carbonate mineral.
Comments:
Unlikely to be from Sardinia(C); Jervis (1889) makes no reference to the commercial working of the minor serpentinite deposits on the island. It may be from the Genoa region, Liguria, Italy, and resembles a variety of marmo verde di Polcevera from Pietra Lavazzara(V), near Campomorone.
